I have W3TC, Nginx, varnish and php5-fpm installed on an Ubuntu 12.04 image with 768 MB RAM. The site itself is functioning fine, but when I try to access \/wp-admin I get an HTTP 500 Internal Server error.<\/p>\n

I have went to the logs and have looked and found the following error:<\/p>\n

\n

PHP message: PHP Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 5184285 bytes) in \/var\/www\/wp-includes\/functions.php on line 251 while reading response header from upstream<\/p>\n<\/blockquote>\n

\n

Increase your allocated memory in wp-config.php or wherever you need it:<\/p>\n

define(‘WP_MEMORY_LIMIT’, ’64M’);<\/p>\n

In case PHP itself is running out of memory, you can increase that by modifying php.ini and restarting your web server.<\/p>\n

memory_limit 256M<\/p>\n<\/blockquote>\n

But haven’t had any luck. I have also restored the image from a previous backup and the issue still exists. No plugins have been modified or updated since the previous time I was able to access the backend.<\/p>\n

I also turned WP_DEBUG to true and saw this:<\/p>\n
