So upon updating this site the other day i received this error and nothing would load. I had a good crack at googling and found a way to resolve it. Either by using FTP/SSH/Cpanel editor, find the wp-config.php file in your site’s home dir and open it to edit. Scroll down to find this line: /* That’s all, stop editing! Happy blogging. */ And add this line just above it: define( ‘WP_MEMORY_LIMIT’, ‘256M’ ); So it should look like: * @link https://codex.wordpress.org/Debugging_in_WordPress */ define(‘WP_DEBUG’, false); define( ‘WP_MEMORY_LIMIT’, ‘256M’ ); /* That’s all, stop editing! Happy blogging. */ Save the file and you should be sorted! Happy days!
