I'm helping run an EE site that's developed a really strange problem that my other EE installs seem to have, even if they are on the same webhost and reseller hosting account.
What's going on is that control panel pages seem to keep getting cached. You'll do an action, and it will clearly be successful (you'll still get the green checkmark) but the reloaded page will be unchanged. Then you'll do a hard refresh on the page, and you'll definitely see it changed. Sometimes this problem is stubborn though, and you'll have to hard reload. This makes it difficult to change almost anything in the CP, like turning add-ons on and off, updating entries, etc.
I feel like this is either a very worrisome problem on a specific EE install, or a trivial issue I can change by updating a setting. Does anyone know why my site might be doing this? Interestingly, the front end of the site is not affected at all.
It sounds like it might be related to this issue but there were no answers suggested.
This site has existed since it was EE1 and went through an EE2 update.
Things I've done:
- cleared all caches in Tools > Data > Clear Cache
— checked that cache folder and subfolder are set to 777
- made sure no template uses Template Caching (even though those are front facing)
I'm running EE 2.9.2 and don't have any exotic caching plugins enabled, though I use Solspace Template Morsels.
