Since many years I run a fairly straightforward Joomla web site on One.Com
One.com runs Maria DB 10.x.
Joomla and everything else is as updated as they should be.
However, the latest CB update attempt failed with the following notice:
"mysql 5.5.5-10.3.32-MariaDB-1:10.3.32+maria~focal is not supported. Minimum required version is mysql 5.6, but it is higly recommended to use mysql 8.0.27 or later".
idem with message :
mysql 5.5.5-10.3.33-MariaDB is not supported. Minimum required version is mysql 5.6, but it is higly recommended to use mysql 8.0.27 or later.
I am under Version du serveur : 10.3.29-MariaDB - MariaDB Server
and I also encounter this same problem MySql mysql 5.5.5-10.3.29-MariaDB is not supported. Minimum required version is mysql 5.6, but it is higly recommended to use mysql 8.0.27 or later
CB 2.7.1 is now released, with a fix for the pre-installation check on MariaDB 10.x.
You might need to hit "Clear Cache" and then "Find updates" button at top of Joomla's extensions update to see CB 2.7.1 release, or "Refresh" at bottom of CB Plugin Installer to see it.
