I am trying to: I had an issue with the site crashing (white screen of death). I've disabled plugins folder then reenabled. Everytime I activate toolset it crashes again. I've updated PHP and am running Generate Press Premium. No other plugins are conflicting.
What you can do is to check the php logs for your server to see if there is any error messages there as well ?
If you're sure how to do this I would recommend that you contact your hosting provider to see if they can provide you with the information in the logs.
