So, I shouldn't use W3 Cache? I shouldn't use cloudflare?
I've disabled W3 and still have the same problems.
Cloudflare protects me from spam bots and other nonsense.
This software won't work if you use cloudflare?
I only said that using all that, it is impossible to test. Use what you like, after you have a stable system.
Never said wpforo doesn't work with something. Still using any caching MUST exclude all of wpForo pages.
Also using DEBUG.LOG could provide you info sometimes about the problem.
Please delete all caches, then deactivate those for a while. Then make sure "HTML Cache" is also disabled in Dashboard > Forums > Settings > Features Tab.
Then press Ctrl+F5 and test it again. Also please leave some URL to allow test it too.
What cache plugin do you suggest?
I need something that will work with cloudflare & my CDN?
I can't figured out how to exclude all the forums in w3TC.
