error: class f0fdatabasedriverjoomla contains 9 abstract methods

[Godchi]

I get this error message that results in error 500: error:

class f0fdatabasedriverjoomla contains 9 abstract methods and must therefore be declared abstract or implement the remaining methods (joomla\database\databaseinterface::getconnectionencryption, joomla\database\databaseinterface::isconnectionencryptionsupported, joomla\database\databaseinterface::isminimumversion, ...)

I was trying to update my joomla from 3.10 to 4.4.0. I have been resolving issues but currently have no solution to this issue.

I also changed class f0fdatabasedriverjoomla to abstract class f0fdatabasedriverjoomla which cleared the error but resulted in another error: Cannot instantiate abstract class F0FDatabaseDriverJoomla.

Please help me guys

Welcome to Joomla forum!

It looks like a 3rd party extension is not compatible with Joomla 4.

Switch on Joomla's debug mode (in Global Configuration or directly in configuration.php) to get a step trace.
The item on top is probably a plugin that causes the issue.

It looks like your template is based on the Warp framework and it is not compatible with Joomla 4. The errors about FoF or F0F come from Akeeba Backup or another extension. It would be better to restore the Joomla 3 version of the website into an empty folder and a new database schema, then update or uninstall the template and update the extension before attempting the Joomla update.
