Hi,
Ok, so...
This is ONLY happening on one of my sites, not on all of them, but my hosting company is claiming it's WF.
I was using WP-Cache before, then I uninstalled it b/c someone said that was conflicting with WF. So then I installed W3 Total Cache & I thought it was working, but when I got this error inside & asked my hosting company about it http://awesomescreenshot.com/0683r1jgd0 they said it was b/c of WordFence & they deactivated it again.
I have not been able to use WF on this site & I don't understand why. Every other site has WF on it.
Please help, my site is unprotected.
Thanks
Michelle
