Pokud systém hlásí, že se nelze dostat do administrace, vyhazuje chybu „Fatal error: Allowed memory size…“ postupujte následnovně
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.
