Thanks for the responses.
@richard I’ve first tried to fix it by adding the following line to wp-config.php “define(‘WP_MEMORY_LIMIT’, ’64M’);”
I did this when my site went blank, didnt solve it.
I havent tried WP_DEBUG yet! thanks for that.
@yurone i have tried this, there is not 1 specific plugin that solves it. its a other every time i think.
Can you tell me more about caching please?
