My site doesn’t show the update version of a page unless you click “refresh” in your browser. The error appears in any browser on any gadget.
It also appears both in the internal and external pages of my site.
E.g. if you deactivate a plugin, you will see it as “deactivated” only after you refresh the plugins page.
I don’t have a cache plugin. I installed one, but didn’t solve the problem.
I deactivated all plugins, but didn’t solve the problem.
I changed the active theme, but didn’t solve the problem.
All my plugins and wordpress version are up to date.
