Cannot Create or Edit Pages

Hi,

We are having some trouble with Page Builder. When we try to edit an existing page or try to create a new one, our browsers go blank.

We do not know exactly when the problem started. We have not edited pages for a while so maybe the problem slipped through unnoticed. Since most content is added via posts we did not notice the issue until we needed to edit an existing page.

We found the problem by deactivating and then reactivating all plugins, until we tracked it when we turned Page Builder off and back on. We then deinstalled the plugin and re-installed it, but it did not fix the issue.

We are using Responsive Theme by CyberChimps and the following plugins:

All in one Favicon

Are there any know issues or does anybody have a tip on how to fix the issue?

Thanks a lot in advance!
