Migrating and Upgrading to Joomla! 4.x • Re: error 500 after update joomla 3 to 4

Hi, I have disabled the forms component but still an error, see go-asia.nl

Disable the plugin, too.
The method isSite() is not available in Joomla 4. Possibly an incompatible template or a menu module.

Caching produces lots of Deprecated errors. Turn off the caching until the errors have been removed, manually by editing the file configuration.php or disabling the plugin.

As @SharkyKZ recommended, restore the last full backup from Joomla 3 into an empty folder and a new database schema. Then post the results of the Forum Post Assistant (FPA) by following the instructions at https://forumpostassistant.github.io/docs/ so that the configuration can be reviewed.
