My Paid Subscription plugin won't install

This is what I get when trying to install the software. Am I missing something?

System Information
Joomla: 3.9.25
PHP: 7.3.27
Database: mysql 5.5.5-10.2.37-MariaDB

Package
File: 002_cbplug_CBSubs_MAIN-4.5.0+build.2021.03.01.06.37.41.6701638db.zip
Log:

Enable debug mode and maximum error reporting in Joomla global configuration then retry to see if the error is exposed in the log. If not try unzipping the installer and installing 002_cbplug_CBSubs_MAIN-4.5.0+build.2021.03.01.06.37.41.6701638db.zip manually from /extensions/cbplugins to CB > Plugin Management > Install CB Plugin and see if any errors are shown.

It didn't work again. I turned on the debug and error reporting and I have a couple of screen shots of the issues it seems almost like a db issue.

Here is the error I received when trying to install the file you suggested.

Row size too large (> 8126). Changing some columns to TEXT or BLOB may help. In current row format, BLOB prefix of 0 bytes is stored inline.

MariaDB is not officially supported. Specifically your issue is discussed in the following topics.

The below topic goes into detail on how to correct MariaDB settings so they more closely match MySQL and should work.

You however are using a very old release of MariaDB and do suggest updating. You may need to contact your host regarding all of this if they don't provide access to make these changes yourself.
