Deleting the cache resulting in white screen

in addition, the correct TEST domain is https:
https://adrobot.nl

and the original (working but slow) is adlads.nl

it seems like a memory problem. is the problem solved when you disable wp fastest cache?

HiEmre,

Thank for the reply;

if I do that it has the same issue: a blank website.

Funny enough the back is still there, pages can be changed etc.
But they are not visible at the front end (logged in or not is the same).

ps

I also unchecked all the tick boxes in the plugin, no change…

we have about 30 sites on the server, all similar setup and some using WPFC, this is the only one with this strange issue,

can you open the admin panel of https://adrobot.nl ? if so, please delete wp fastest cache.

deleted now

the page is still not working.

exactly that is the point
(exact same installation still exists on adlads.nl, only diff is the cache not cleared and plugin not deleted)

Please deactivate and delete wp fastest cache plugin.

that will bring adlads.nl down too
this is the reason I have cloned the site to adrobots.nl

on adrobots.nl the plugin has been removed

adrobot.nl
