All of a sudden, out of nowhere about a day ago this happened. Since then, I’ve tried moving hosts and it still didn’t work, so that’s when I concluded that it had something to do with wordpress, as my forum has always worked, no problem.
1. Try adding this line to your wp-config.php file:
define('WP_MEMORY_LIMIT', '64M');
2. If you have access to your PHP.ini file, change the line in PHP.ini
If your line shows 32M try 64M:
memory_limit = 64M ; Maximum amount of memory a script may consume (64MB)
3. If you don't have access to PHP.ini try adding this to an .htaccess file:
php_value memory_limit 64M
4. Talk to your host.
Don’t know where php.ini is located, so I couldn’t edit that. I also don’t know how my host would help, as I’ve completely changed hosts from one to another and I’m still getting the same problem.
To find any theme-specific problem, just access your server via FTP or SFTP, navigate to /wp-content/themes/ and rename every directory except the /default/ directory. This will force the Default theme to activate.
