I am experiencing the same problem. It all started once I updated ZenCache on Monday. All In One and Google Sitemap then began failing miserably. All In One is now deactivated (.htaccess has updates from All In One settings) then I activated Google Sitemap yesterday and so far the site is working properly.
I am working with the Authors of ZenCache to determine if their new version is causing issues with the 2 plugins mentioned above but so far no smoking gun. I can say state though that my 2 other sites are using PHP 5.3 + extension using the same plugins and are working fine. This site having trouble is on PHP 5.4. Coincidence?
See my conversation with ZenCache on GitHub here: https://github.com/websharks/zencache/issues/515#issuecomment-117818407
If you are using ZenCache, upgraded to version 150626, using PHP 5.4 and experiencing the white page of death, downgrade to the prior version of ZenCache.
@amazinghulk can you test one of WordPress default themes, for example WordPress default themes Twenty Fourteen.
@eclerkin can you start a new thread please.
Thank you
Thanks for reply,
I tried deactivate/activate WP Security with Twenty Fifteen theme and confirm that error doesnt show then.
When I try with theme I use, error appers instantly when I choose to import previous plugin .htaccess rules (it doesnt appear when I activate plugin)
So I guess problem is because of some settings I enabled in plugin.
But which one?
edit: I dont use ZenCache. But do use Supercache.
@amazinghulk try to enable one by one the features and see which one is causing the problem. I think one or more of the features you enable is causing a problem with your cache plugin.
Will try that then and let you know.
PS: Error appears in both cases. When super cache plugin is deactivated or activated.
Thank you, I look forward to your message.
Is your issue now resolved?
I am marking this thread as resolved. No replies in 8 months.
