Warnings & Post Installation Messages
There are two kinds of messages to pay attention to after you update your Joomla! CMS:
- POST INSTALLATION MESSAGES, and
- WARNINGS displayed in the Extensions > Warnings screen.
We recommend that you review Post-installation Messages immediately after updating the Joomla! CMS.
If there are any NEW messages after you update your website's Joomla! CMS then you will see a BELL (see image) at the top of the website Dashboard.
You will also see a YELLOW BOX displayed next to Installation Messages in the System Dashboard screen.
Messages should not be hidden until you have read them.
And SECURITY messages should NEVER be ignored.
Once you have dealt with messages they can however be hidden away.
You can check for Warnings in the Information Panel of the System Dashboard.
If you don't see a TICK next to Warnings then you know there are problems (as shown in the image below).
