There are quite a few plugins that Comet Cache does not detect changes to. (e.g. contact form 7)
I run multisite, and unfortunately this leaves sites with cached pages. Is there any way to allow site admins to clear the cache on their own sites?
Allowing Site Admins to Clear their own cache
@trex005 Comet Cache relies on plugins using the appropriate WordPress hooks to trigger a clearing of the cache when it’s necessary, or to indicate when a page should not be cached (the constant that all WordPress caching plugins watch for is DONOTCACHEPAGE and it’s up to each plugin to utilize this standard).
We have a GitHub issue open with regards to Contact Form 7; see this GitHub issue.
Regarding allowing site admins to clear the cache in WordPress Multisite: Comet Cache Pro allows you to control which WordPress Roles/Capabilities are allowed to see the Clear Cache button in the admin toolbar:
If you add administrator to that list, then any user with the Administrator role will be able to see the Clear Cache button when logged into their site and clicking that button will clear the cache for their site:
If you’re using Comet Cache Lite, you can see that section by enabling the Pro Preview and then visiting Comet Cache → Plugin Options → Manual Cache Clearing.
