I have spent weeks trying to find a solution to this issue. Basically Joomla administrator maintenance (deletion of records from tables) has become near impossible with Cloudflare enabled.
I regularly need to delete records on mass from various components. I used to be able to select 100+ records at any one time and delete them without problem, now it seems to crash if I select 6+ records and shows the Cloudflare timeout error.
I tried installing the mod_cloudflare as suggested in your getting started with Joomla article but it broke my site so had to remove it. I have also tried creating page rules to ignore all administrator areas of my site - it doesn’t do anything.
What do I have to do to get cloudflare with my Joomla administration? I basically don’t wnt cloudflare doing anything in the administrator area.
Any help/advice would be greatly appreciated
