Our 8 sites were running with version 2.5.23 and Cloudflare for months without problems… Until today when I decided to do the update to 2.5.24.
Immediately it returned 502 Bade Gateway errors over Cloudflare. I can’t even get normal access to my dashboard. It returned 502 bad gateway errors.
Even when I trashed Really SSL and deactivated Cloudflare it keeps returning me 502 bad gateway errors. I have cleared all caches (browsers, Cloudflare, etc.) and it keeps returning the 502.
I checked my files and saw that at the same time I did the update, the .htaccess and wp-config files were changed.
The plugin is not compatbile with Cloudflare and probably it altered some settings in such a way somewhere in Cloudflare that it keeps producing 502 errors, throwing old content and 502 errors.
Since we’ve been using this plugin for more than 1 yr without any problems, the update must have triggered corruption.
We’re now working for hours to make everything working again.
