Title: [Plugin: Register Plus Redux] call_user_func_array() error Last modified: August 19, 2016 --- # [Plugin: Register Plus Redux] call_user_func_array() error * Resolved [Richard Archambault](https://wordpress.org/support/users/richardmtl/) * (@richardmtl) * [15 years, 7 months ago](https://wordpress.org/support/topic/plugin-register-plus-redux-call_user_func_array-error/) * So I have a WordPress install with no plugins active except for Register Plus Redux, using TwentyTen (unmodified). I am testing this plugin, and all the options look great, but there are 3 issues: * 1) the biggest issue is that when a user clicks on “Register”, they get this: * Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, ‘Array’ was given in /home/*****/public_html/***. com/wp-includes/plugin.php on line 166 * Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, ‘Array’ was given in /home/****/public_html/***. com/wp-includes/plugin.php on line 166 * Warning: Cannot modify header information – headers already sent by (output started at /home/****/public_html/***.com/wp-includes/plugin.php:166) in /home/richm**** tl/public_html/****.com/wp-includes/pluggable.php on line 890 * I’ve tried to register without the plugin, and no error. I’ve tried the plugin with no options other than the ones that send emails to admin and the user, and I still get this message. * 2) the email that i get as an admin (using the “send as HTML” option) are sent as wierd attachments and not in the body-text of the email * 3) the email sent says the following: * New user registered on your site * Username: unverified_XVu1ylU E-mail: (private) * that username is not very pretty, and is not what I wrote as a username. * So what’s going on here? Is it something with my server configuration?? * [http://wordpress.org/extend/plugins/register-plus-redux/](http://wordpress.org/extend/plugins/register-plus-redux/) Viewing 12 replies - 1 through 12 (of 12 total) * Plugin Author [radiok](https://wordpress.org/support/users/radiok/) * (@radiok) * [15 years, 7 months ago](https://wordpress.org/support/topic/plugin-register-plus-redux-call_user_func_array-error/#post-1711573) * I can’t recreate 1 or 2 with 3.6.14, the version I am preparing for production, so please, give that a try. As for issue 3, while the user is in queue to be verified they get that ugly username, it’s actually a random string, that way, they can’t login. If we did not do that, it would be pretty difficult to build a user verification system. I could add another keyword so you could create a custom message with the desired username as opposed to the system assigned username. * Can you give 3.6.14 a shot, and let me know what you think about the username? * Thread Starter [Richard Archambault](https://wordpress.org/support/users/richardmtl/) * (@richardmtl) * [15 years, 7 months ago](https://wordpress.org/support/topic/plugin-register-plus-redux-call_user_func_array-error/#post-1711575) * Hi! * I’d love to try out .14, but I can’t find the download.. I hate how WP has changed the plugin pages.. 🙁 * Can you point me to a zip? I looked at the blog, at the “other versions”, everywhere, and I can’t find it. Maybe it hasn’t been approved from the plugin qeueu yet?( there is one, right?) * As for the username, my main concern is for my client, he might be confused when he sees that. I think your suggestion of a keyword, such as %chosen_username%, would be excellent, and maybe even make it default in the message sent to the admin? 🙂 * BTW, I think you’re doing excelent work all around.. This is the kind of functionality that should be in the Core, IMHO! 🙂 * Plugin Author [radiok](https://wordpress.org/support/users/radiok/) * (@radiok) * [15 years, 7 months ago](https://wordpress.org/support/topic/plugin-register-plus-redux-call_user_func_array-error/#post-1711586) * 3.6.14 in online at WordPress now, you’re right though, there’s a queue the plugin has to go through before it gets posted. Well, maybe not a queue, but it definately doesn’t happen immediately. Regardless, I added a new keyword %stored_user_login%, you can use that keyword to get the username as requested by the user. * Thanks for your encouragement, maybe somebody at WordPress will have the same idea sometime! I wouldn’t mind a new job! * Thread Starter [Richard Archambault](https://wordpress.org/support/users/richardmtl/) * (@richardmtl) * [15 years, 7 months ago](https://wordpress.org/support/topic/plugin-register-plus-redux-call_user_func_array-error/#post-1711588) * I still get the same damn error.. 🙁 * I’ll reinstall WP, and I’ll try it on another site as well, see if I can reproduce elsewhere.. * Plugin Author [radiok](https://wordpress.org/support/users/radiok/) * (@radiok) * [15 years, 7 months ago](https://wordpress.org/support/topic/plugin-register-plus-redux-call_user_func_array-error/#post-1711600) * Yeah, let me know, there’s also some debugging code you could turn on to try and track this down. Let me know if it’s an isolated issue or not. * Thread Starter [Richard Archambault](https://wordpress.org/support/users/richardmtl/) * (@richardmtl) * [15 years, 7 months ago](https://wordpress.org/support/topic/plugin-register-plus-redux-call_user_func_array-error/#post-1711604) * I got the same problem on another site (same server, though..) * I’ll try with a different site. * Thread Starter [Richard Archambault](https://wordpress.org/support/users/richardmtl/) * (@richardmtl) * [15 years, 7 months ago](https://wordpress.org/support/topic/plugin-register-plus-redux-call_user_func_array-error/#post-1711609) * So I tried it on a different server, still getting the same thing. I activated all the options I wanted, however. Not sure what else I can do.. * I tried again on the different server, but this time I only left the “moderate new users” option active 9turned off everything else).. Maybe it has something to do with the messages? * And you know what? I’m either expericneing deja vu, or I wen tthrough the same thing with the Absolute Privacy plugin once.. let me check and get back to you. * Thread Starter [Richard Archambault](https://wordpress.org/support/users/richardmtl/) * (@richardmtl) * [15 years, 7 months ago](https://wordpress.org/support/topic/plugin-register-plus-redux-call_user_func_array-error/#post-1711610) * Sorry, can’t find if I posted this already with Absolute Privacy. maybe it’s my imagination.. * Any other ideas about how to troubleshoot this? * [Shrikant Joshi](https://wordpress.org/support/users/shrikantjoshi/) * (@shrikantjoshi) * [15 years, 7 months ago](https://wordpress.org/support/topic/plugin-register-plus-redux-call_user_func_array-error/#post-1711659) * Yup! I just tested 3.6.14 creating a new user from the dashboard and I got the same message, too! * > Subject: New User Registration: %user_login% * The rest of the message is empty but the funny thing is: All the user details are attached in a dat file called ‘noname.dat’! I The message as seen on my BlackBerry give a li’l more info: it says, “Unsupported media type in header.” * I have now changed the replacement keyword to %stored_user_login% – let’s hope this works! * Cheers! * PS: I see you’ve pushed 3.6.15 – I’ll check & repost if the problem continues to persist. 🙂 * [Shrikant Joshi](https://wordpress.org/support/users/shrikantjoshi/) * (@shrikantjoshi) * [15 years, 7 months ago](https://wordpress.org/support/topic/plugin-register-plus-redux-call_user_func_array-error/#post-1711660) * Okay, just checked v3.6.15 – here’s the report: * Added a user via Dashboard in WP & there’s only one tiny problem so far: * The Email subject line still says %stored_user_login% instead of the username chosen!! Neither the variable nor the actual username appears in the body! The same happens when a user tries to register using the front-end form. 🙁 * Also, in the list of users, unverified users appear with the “temp username” instead of the “requested username: – it’s not a big deal, actually. Just reporting it. 🙂 * Once again, thanks for all the effort! * Plugin Author [radiok](https://wordpress.org/support/users/radiok/) * (@radiok) * [15 years, 7 months ago](https://wordpress.org/support/topic/plugin-register-plus-redux-call_user_func_array-error/#post-1711674) * Your first problem is pretty simple, I don’t check the subject against keywords. I’ll add that in today, it’s a quick easy fix. Are you still getting the jacked up emails saying unsupported media type? * [Shrikant Joshi](https://wordpress.org/support/users/shrikantjoshi/) * (@shrikantjoshi) * [15 years, 7 months ago](https://wordpress.org/support/topic/plugin-register-plus-redux-call_user_func_array-error/#post-1711679) * Forgot to mention that – the 3.6.15 update contained all the data WITHIN the mail and NOT in a .dat attachment – I had meant to say that 3.6.15 had partially solved the issue. * I upgraded to 3.6.16 but haven’t gotten around to testing the update yet. Will check & post back soon, hopefully. 🙂 * Thanks a zillion! 🙂 Viewing 12 replies - 1 through 12 (of 12 total) The topic ‘[Plugin: Register Plus Redux] call_user_func_array() error’ is closed to new replies. * ![](https://s.w.org/plugins/geopattern-icon/register-plus-redux.svg) * [Register Plus Redux](https://wordpress.org/plugins/register-plus-redux/) * [Frequently Asked Questions](https://wordpress.org/plugins/register-plus-redux/#faq) * [Support Threads](https://wordpress.org/support/plugin/register-plus-redux/) * [Active Topics](https://wordpress.org/support/plugin/register-plus-redux/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/register-plus-redux/unresolved/) * [Reviews](https://wordpress.org/support/plugin/register-plus-redux/reviews/) * 12 replies * 3 participants * Last reply from: [Shrikant Joshi](https://wordpress.org/support/users/shrikantjoshi/) * Last activity: [15 years, 7 months ago](https://wordpress.org/support/topic/plugin-register-plus-redux-call_user_func_array-error/#post-1711679) * Status: resolved
