I am experiencing a major error with trying to log in to the admin area of my website (I've seen it called the "White Screen of Death" too). When I try to access <www.themusicphoenix.com/wp-admin> I get "HTTP Error500 (Internal Server Error): An unexpected condition was encountered while the server was attempting to fulfill the request."
According to my error log, the following issues have happened:
[10-Aug-2012 00:19:51] PHP Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 13987004 bytes)in wp-includes/class-http.php on line 1154
[10-Aug-2012 18:27:50] PHP Fatal error: Call to undefined function get_theme_data() in wp-content/themes/mystique/atom-core.php on line 143
[13-Aug-2012 06:52:29] PHP Fatal error: Call to undefined function wp_load_translations_early() in wp-includes/functions.php on line 1129"
About 4 days ago, I wrote a new post on the website; the main page loads, but shows that post as only 17 hours old. The website isn't able to notice what time or day it is either. (not sure if that detail will help or not)
Here are a number of things I have tried without luck:
-refreshing my computer's cache
-restoring my most recent backup, restoring last week's backup and restoring last month's backup
-deactivating the plugins through the FTP
-deactivating the cache through FTP
-creating the php.ini to add the memory=20mb
-editing the .htaccess & deleting and recreating the .htaccess
-uninstalling wordpress and restoring the backup
I am up to date with all of the updates, in fact it was right after the update of "viper video quicktags" when the site went into this error.
-I have tried deleting that plugin from the FTP and the problem still exists
-I've also been in phpMyAdmin to try those suggestions.
I'm not sure how to deactivate a theme without accessing the actual admin page.
As you can tell, I have tried just about every suggestion I could get my hands on. I really don't want to scrap the website and start over - I have nearly 450 posts on this website that I would lose. Please help me!
