the cache appears not to be working.
Although enabled, I do not see the cache status message at the end of the html source
I just realized that now, so I do not know if it stopped working after the last update or something else is the problem.
When I use the cache tester, I receive this message:
The pages do not match! Timestamps differ or were not found!
I have used this plugin for more than a year without any problems until now.
