Title: Incomplete plugin breaks wordpress? Last modified: August 19, 2016 --- # Incomplete plugin breaks wordpress? * [sayakb](https://wordpress.org/support/users/sayakb/) * (@sayakb) * [17 years, 5 months ago](https://wordpress.org/support/topic/incomplete-plugin-breaks-wordpress/) * hello.. I probably spoiled my installation. I uploaded a plugin that was incomplete, and activated it. When I tried to open wp-admin/plugins.php or wp-admin/plugin- install.php, it prompted me to download the files instead. So I deleted the plugin— and wordpress told be that it deactivated the plugin as it doesnt exist. Now each time I upload a plugin, it does not open plugins.php but prompts me to download it. Also, plugin-install.php never opens (always prompts for download) Viewing 6 replies - 1 through 6 (of 6 total) * Thread Starter [sayakb](https://wordpress.org/support/users/sayakb/) * (@sayakb) * [17 years, 5 months ago](https://wordpress.org/support/topic/incomplete-plugin-breaks-wordpress/#post-934726) * Update: plugins.php opens okay now. And.. plugin-install.php opened this morning. But it had this error at the end: Warning: http_build_query() expects at most 2 parameters, 3 given in /home/www/blog.sayakbanerjee.com/wp-includes/http.php on line 248 * So I opened up http.php and found this code: $r[‘body’] = http_build_query($ r[‘body’], null, ‘&’); * And replaced this with this (in order to have 2 args): $r[‘body’] = http_build_query( $r[‘body’], ‘&’); * So well, that again made plugin-install.php disappear with the “Download this file” syndrome. I changed the code back, while plugin-install.php isn’t back again. * So in a nutshell: 1. I have akismet and hello dolly plugins in my wp-content/ plugins folder. Not the faulty sociable plugin anymore. * 2. Everything in my dashboard works fine, **except** for plugin-install.php ( Install new plugins). That means I cannot have more plugins but only the default ones. * [platypusman](https://wordpress.org/support/users/ungeziefer/) * (@ungeziefer) * [17 years, 4 months ago](https://wordpress.org/support/topic/incomplete-plugin-breaks-wordpress/#post-934871) * Getting the exact same error: * http_build_query() expects at most 2 parameters, 3 given in … wp-includes/http. php on line 248 * What’s weird is that I have a recent, fresh WordPress install with no plugins whatsoever. So I think this is a WordPress bug — not something you (or I) did. * If I figure out the problem I will post back. * thanks, * dustin * Moderator [Samuel Wood (Otto)](https://wordpress.org/support/users/otto42/) * (@otto42) * WordPress.org Admin * [17 years, 4 months ago](https://wordpress.org/support/topic/incomplete-plugin-breaks-wordpress/#post-934872) * That doesn’t make any sense, because http_build_query takes THREE parameters, not two. See here: [http://www.php.net/http_build_query](http://www.php.net/http_build_query) * The function is also defined in wp-includes/compat.php for those peoplee running older php versions. * [mediafetish](https://wordpress.org/support/users/mediafetish/) * (@mediafetish) * [17 years, 4 months ago](https://wordpress.org/support/topic/incomplete-plugin-breaks-wordpress/#post-934893) * I might be mistaken but I found that in version 5.1.2 of PHP the arg_separator parameter was added. I’m running 5.0.4 – I have the function, but not the third parameter. So I’m getting the same error. * [sjordan](https://wordpress.org/support/users/sjordan/) * (@sjordan) * [17 years, 3 months ago](https://wordpress.org/support/topic/incomplete-plugin-breaks-wordpress/#post-934913) * My web server was upgraded to the 5.0.3 version of PHP and I got that warning. I had the server reverted back to PHP Version 4.3.11 and there is no warning and I can install plugins. I also have no warning message and proper function while using PHP Version 5.2.8. * [jonja](https://wordpress.org/support/users/jonja/) * (@jonja) * [17 years, 3 months ago](https://wordpress.org/support/topic/incomplete-plugin-breaks-wordpress/#post-934919) * having same error when in plugins_install page if doing anything that needs a search… ( okay on Start page).. * Warning: http_build_query() expects at most 2 parameters, 3 given in /home/…./ wp-includes/http.php on line 251 * Everything was fine before ! the last plugin I activated was WASSUP so I deactivated but the problem still there. I did upgrade my php version from 4+ to 5.02 two days ago but I think (as far as I recall) I did not have this error afterwards! * **Okay, I did another upgrade on my php version to 5.2 and all works fine now– the error disappeared on all plugin-install pges and I installed new plugin with no problem !** Viewing 6 replies - 1 through 6 (of 6 total) The topic ‘Incomplete plugin breaks wordpress?’ is closed to new replies. * 6 replies * 6 participants * Last reply from: [jonja](https://wordpress.org/support/users/jonja/) * Last activity: [17 years, 3 months ago](https://wordpress.org/support/topic/incomplete-plugin-breaks-wordpress/#post-934919) * Status: not resolved ## Topics ### Topics with no replies ### Non-support topics ### Resolved topics ### Unresolved topics ### All topics
