Title: WordPress 4.0 Breaking Last modified: August 22, 2016 --- # WordPress 4.0 Breaking * [mashwebdesign](https://wordpress.org/support/users/mashwebdesign/) * (@mashwebdesign) * [11 years, 8 months ago](https://wordpress.org/support/topic/wordpress-40-breaking/) * Hi, * I have used contact form 7 a lot in the past, however when i have tried to install cf7 in my first wp 4.0 project, the admin breaks? I have deleted the files and retried through the installer but with no luck, have you seen this issue before? * Adam * [https://wordpress.org/plugins/contact-form-7/](https://wordpress.org/plugins/contact-form-7/) Viewing 12 replies - 1 through 12 (of 12 total) * [Rob W](https://wordpress.org/support/users/robertark/) * (@robertark) * [11 years, 8 months ago](https://wordpress.org/support/topic/wordpress-40-breaking/#post-5269865) * Need more info. Any error messages? Are you sure it’s CF7? I haven’t had a problem with it in WP4 * [cocoonfxmedia](https://wordpress.org/support/users/cocoonfx/) * (@cocoonfx) * [11 years, 8 months ago](https://wordpress.org/support/topic/wordpress-40-breaking/#post-5269912) * I am also experiencing problems with wp 4.0 only the text area is showing and the email to and name fields aren’t showing. It seems the css isn’t pulling through from contact form 7. * [jeffunderwoodWP](https://wordpress.org/support/users/jeffunderwoodwp/) * (@jeffunderwoodwp) * [11 years, 8 months ago](https://wordpress.org/support/topic/wordpress-40-breaking/#post-5269916) * Same problem here, with this page -http://www.mp3bymail.com/contact-us/ * I got three emails yesterday, each came through fine. Then I upgraded to WP 4 and the messages thereafter have all failed. * When I go through to the mail database via the WP control panel I can see the messages people have tried to send. * [Rob W](https://wordpress.org/support/users/robertark/) * (@robertark) * [11 years, 8 months ago](https://wordpress.org/support/topic/wordpress-40-breaking/#post-5269928) * Are you using akismet in the fields that aren’t working? If so, move the akismet attribute to be after the field name. * [3001web](https://wordpress.org/support/users/2001web/) * (@2001web) * [11 years, 8 months ago](https://wordpress.org/support/topic/wordpress-40-breaking/#post-5269964) * Has the plugin been fully tested on version 4 of wordpress? Is there going to be an update? * [Neil Murray](https://wordpress.org/support/users/buzztone/) * (@buzztone) * [11 years, 8 months ago](https://wordpress.org/support/topic/wordpress-40-breaking/#post-5269965) * @cocoonfxmedia, [@jeffunderwoodwp](https://wordpress.org/support/users/jeffunderwoodwp/)& [@2001web](https://wordpress.org/support/users/2001web/) – The plugin is working for me on WP 4.0 on a few different websites. You will probably be mistaken if you focus on this happening since the last update – it’s most likely just a coincidence. * [Neil Murray](https://wordpress.org/support/users/buzztone/) * (@buzztone) * [11 years, 8 months ago](https://wordpress.org/support/topic/wordpress-40-breaking/#post-5269966) * [@mashwebdesign](https://wordpress.org/support/users/mashwebdesign/) – try deleting the plugin folder at wp-content/plugins/contact-form-7/ and then install the plugin again. * Next try following: ​ **Step by step approach to finding problems** * 1. Switch temporarily to a WordPress default theme (Twenty Eleven etc.) and see if the problem goes away. * If it does, you’ve most likely got a JavaScript conflict with your current WordPress theme. * If switching to default theme doesn’t help it could be one of the plugins you are using that is causing the problem. * 2. Disable all plugins other than Contact Form 7 * If doing that solves the problem, you can then add back each item – one by one, until you find the cause of the problem.​​ * [jeffunderwoodWP](https://wordpress.org/support/users/jeffunderwoodwp/) * (@jeffunderwoodwp) * [11 years, 8 months ago](https://wordpress.org/support/topic/wordpress-40-breaking/#post-5269972) * Yesterday was a very, very bad day. A couple of minutes after posting yesterday my website was taken down by my host. When I submitted a bug report they (eventually) told me my account had been hacked. You can imagine but I hope never experience, the rest of the day. * Thankfully I found the great people at Securi who for a modest subscription sorted it all out for me. They gave me a list of all the infected files and indeed some were associated with CF7. Late yesterday, after some negotiation with my hosting people, the site was put back up. That gave me all I had before (WP 4 plus CF7) and I’m pleased to say it does all work OK now. * I have to agree with buzztone – it was a coincidence, of the very worst kind. * [cocoonfxmedia](https://wordpress.org/support/users/cocoonfx/) * (@cocoonfx) * [11 years, 8 months ago](https://wordpress.org/support/topic/wordpress-40-breaking/#post-5269973) * It seems to be working a member of staff left a id of a css which hide the form. Sorry.. * Thread Starter [mashwebdesign](https://wordpress.org/support/users/mashwebdesign/) * (@mashwebdesign) * [11 years, 8 months ago](https://wordpress.org/support/topic/wordpress-40-breaking/#post-5269991) * Hi Guys, * Thanks for all of the replies, i have been away. * The error i am getting after enabling wp_debug is: * Fatal error: Allowed memory size of 41943040 bytes exhausted (tried to allocate 7680 bytes) in /Users/adamcollins/Documents/Sites/Mash Clients/Shire/wp-admin/ includes/list-table.php on line 66 * If any of you WP Masters! can share some advice id be seriously appreciative. * Adam * Thread Starter [mashwebdesign](https://wordpress.org/support/users/mashwebdesign/) * (@mashwebdesign) * [11 years, 8 months ago](https://wordpress.org/support/topic/wordpress-40-breaking/#post-5269992) * Also, tried using twenty fourteen theme and installing it but still have the issues. * [Neil Murray](https://wordpress.org/support/users/buzztone/) * (@buzztone) * [11 years, 8 months ago](https://wordpress.org/support/topic/wordpress-40-breaking/#post-5270023) * [@mashwebdesign](https://wordpress.org/support/users/mashwebdesign/) – Part 2 of the step by step approach I suggested above is equally important. In your case running out of memory is a further indicator of a plugin issue.
