After doing a facelift for my company's site, I was re-enabling all my plugins including some new ones. I have been using W3 Total Cache before, and after testing everything out I enabled it last.
The result was a blank screen in the admin. Strangely, the public-facing web pages continued to work, but I a received nothing but blank pages whenever I tried to access any admin page.
I manually removed W3 Total Cache to get the admin back up again, and experimented to find out what was causing the issues, as this had not happened before. I was able to deduce that W3 Total Cache was causing this blank out when this plugin was enabled:
WordPress Contact Form Plugin by vCita
Along with enabling either WP-PageNavi or WP Customer Reviews (or enabling both).
I was wondering if you might be able to deduce what the issue is and provide a possible solution. Thanks!
