Title: WordPress Crashed after update Last modified: August 20, 2016 --- # WordPress Crashed after update * [acrono](https://wordpress.org/support/users/acrono/) * (@acrono) * [13 years, 11 months ago](https://wordpress.org/support/topic/wordpress-crashed-after-update/) * I updated to 3.4.1 this morning and everything crashed on my blog. * Check the errors here: tuningforge.com * ``` Warning: Parameter 1 to update_comment_type_cache() expected to be a reference, value given in /home/a8503hos/public_html/tuningforge.com/wp-includes/plugin.php on line 227 Warning: Invalid argument supplied for foreach() in /home/a8503hos/public_html/tuningforge.com/wp-includes/query.php on line 2762 ``` Viewing 13 replies - 1 through 13 (of 13 total) * [Jarret](https://wordpress.org/support/users/jarretc/) * (@jarretc) * [13 years, 11 months ago](https://wordpress.org/support/topic/wordpress-crashed-after-update/#post-2855118) * I’m hoping you have a backup before the upgrade? If so, reload the backup and then you can try updating again. * You could also create a test install with a copy of your site’s data on a separate domain or a subdomain of your current domain and try updating that way and in the future to make sure things don’t break on your live site. * Thread Starter [acrono](https://wordpress.org/support/users/acrono/) * (@acrono) * [13 years, 11 months ago](https://wordpress.org/support/topic/wordpress-crashed-after-update/#post-2855121) * I don’t have a backup of my site. I can make a database backup anyway (i can access the admin panel). * Hope you guys know what’s causing this. * Can I downgrade the wordpress version ? * [addsystems](https://wordpress.org/support/users/addsystems/) * (@addsystems) * [13 years, 11 months ago](https://wordpress.org/support/topic/wordpress-crashed-after-update/#post-2855165) * Hi Acrono, * I saw the same issue except my entire site is down, admin too. You can rollback on a WP version easily by going to * [http://wordpress.org/download/release-archive/](http://wordpress.org/download/release-archive/) * Select the version you want, unzip it and then using an FTP app like FileZilla, overwrite the wp-admin and wp-includes folder and also all the root files (except wp-config) with the newly unzipped version files. * This will get you back to the version you selected without affecting your themes, plugins etc. * I’ve done this loads of times through the years when I make a mess of things. * Hope this helps, GB * [esmi](https://wordpress.org/support/users/esmi/) * (@esmi) * [13 years, 11 months ago](https://wordpress.org/support/topic/wordpress-crashed-after-update/#post-2855166) * No! That will not work if the database has also been upgraded. * [addsystems](https://wordpress.org/support/users/addsystems/) * (@addsystems) * [13 years, 11 months ago](https://wordpress.org/support/topic/wordpress-crashed-after-update/#post-2855168) * Ah yes, I forgot about the db upgrade. Apologies for the misleading suggestion. * Can you suggest a solution esmi? * [esmi](https://wordpress.org/support/users/esmi/) * (@esmi) * [13 years, 11 months ago](https://wordpress.org/support/topic/wordpress-crashed-after-update/#post-2855186) * You would first have to restore a pre-upgrade database backup, then upload the relevant version of WordPress that matches your database version. * Thread Starter [acrono](https://wordpress.org/support/users/acrono/) * (@acrono) * [13 years, 11 months ago](https://wordpress.org/support/topic/wordpress-crashed-after-update/#post-2855284) * I don’t have a previous database backup. How can we solve this ? * [esmi](https://wordpress.org/support/users/esmi/) * (@esmi) * [13 years, 11 months ago](https://wordpress.org/support/topic/wordpress-crashed-after-update/#post-2855285) * Try: – switching to the Twenty Eleven theme by renaming your current theme’s folder inside wp-content/themes and adding “-old” to the end of the folder name using [FTP](http://codex.wordpress.org/FTP_Clients) or whatever file management application your host provides. * – [resetting the plugins folder](http://codex.wordpress.org/FAQ_Troubleshooting#How_to_deactivate_all_plugins_when_not_able_to_access_the_administrative_menus.3F) by FTP or phpMyAdmin. * – re-uploading all files & folders – **except** the wp-content folder – from a **fresh** download of WordPress. * – running the upgrade manually via wp-admin/upgrade.php * Thread Starter [acrono](https://wordpress.org/support/users/acrono/) * (@acrono) * [13 years, 11 months ago](https://wordpress.org/support/topic/wordpress-crashed-after-update/#post-2855325) * I switched to Twenty Eleven by admin panel. This theme seems to be causing no problem. So it’s a theme problem here. * [esmi](https://wordpress.org/support/users/esmi/) * (@esmi) * [13 years, 11 months ago](https://wordpress.org/support/topic/wordpress-crashed-after-update/#post-2855326) * What theme were you using previously? * Thread Starter [acrono](https://wordpress.org/support/users/acrono/) * (@acrono) * [13 years, 11 months ago](https://wordpress.org/support/topic/wordpress-crashed-after-update/#post-2855352) * Theme: Magnet by WpZoom * [esmi](https://wordpress.org/support/users/esmi/) * (@esmi) * [13 years, 11 months ago](https://wordpress.org/support/topic/wordpress-crashed-after-update/#post-2855363) * Try posting on WP Zoom’s forums: [http://www.wpzoom.com/support/](http://www.wpzoom.com/support/) * [stupid_moron](https://wordpress.org/support/users/stupid_moron/) * (@stupid_moron) * [13 years, 4 months ago](https://wordpress.org/support/topic/wordpress-crashed-after-update/#post-2855516) * Hi, * I hope someone can help. I just tried to upgrade to the latest version of WordPress and it hung. Now all I can get is; * “Fatal error: Call to undefined function wp() in /home/CPANEL_USERNAME/public_html/ wp-blog-header.php on line 14” * Is there anything I can do to get back to where I was before I tried to upgrade? * I was just about to install a backup plugin – please tell me that my work is not gone forever. * I know I’m really dumb for asking this, but why can’t the WordPress install system first look to see if there is enough space, stop if there isn’t and otherwise make a backup of anything needed to get the site back up again? I’m sure WordPress’ tech people are sick of dealing with this issue, so what is so hard about implementing what I just suggested?
