I have version 5.1.2 in WordPress 6.6.1 and tried to upgrade to 5.0.0. I believe my current install is Piwik. I downloaded the zip file and uploaded it to my plugins directory using FTP binary transfer. I received a fatal plugin error from WordPress.
When seeking help with this issue, you may be asked for some of the following information:
WordPress version 6.6.1
Active theme: Avada Child (version 1.0.0)
Current plugin: (version )
PHP version 8.3.8Error Details
An error of type E_ERROR was caused in line 42 of the file

When I logged into WordPress it had deactivated Matomo due to missing a valid header. I restored 5.1.2.
Any suggestions?
