Yes, cache function is cache plugin.
If the issue is solved if you disable the cache, that can mean that one of your plugins is not cache friendly.
I'll tell you what I would do in your place. Deactivate all plugins except for the cache plugin, purge the cache and test whether the problem still occurs. If not, activate each plugin individually and after each activation of the respective plugin, purge the cache again and test if the problem occurs. You repeat this step after each plugin activation to find out which plugin is causing the problem. Understood everything?
