Hi there
I have been successfully using JLex Comment for many months now, however all of a sudden I cannot get new published comments to show, without manually clearing the master Joomla Cache first. There is no information in your official Documentation about these Advanced Settings.
1. When a guest (public user) posts a new comment, it remains hidden until the Admin publishes the comment - this is correct.
2. After the Admin publishes the comment and you refresh the webpage, the comment should then be visible to Public Users, but it is not.
3. If a Registered User then logs into the website, the new published comment is now visible - however if the Registered User then logs out again, the published comment then disappears again, even though it has been published and approved - it should not be doing this.
4. The only way I can get new Public Comments to show, is to manually clear the master Joomla cache, after approving/publishing Public Comments.

Here are my current settings:
JLex Comment = v1.4.8
Joomla = 3.8.7
PHP = 7.2.1

Joomla Cache Settings:

JLex Advanced Settings:

I can't work out what changed ?
Was it something in Jlex comment v 1.4.8 ?
