Hello,

I tried to uninstall some plugins in one of the slaves sites and it returns a fatal error.

JMS version 1.3.41 - Joomla 3.3.6

Catchable fatal error: Argument 2 passed to JAdapterInstance::__construct() must be an instance of JDatabaseDriver, none given, called in /home/account/subdomains/mastersite/public_html/administrator/components/com_multisites/libraries/joomla/installer/installer_multisites.php on line 532
and defined in
/home/account/subdomains/mastersite/public_html/libraries/joomla/base/adapterinstance.php on line 46

Can you precise how you uninstall some plugins ?

I have tried uninstalling the plugin with the JMS Tool menu and it succeed.
Can you precise the produce to help us reproducing it.

I'm getting the same bug aswell

I unninstall plugins on the backoffice ->extension manager->manage (select and uninstall plugins), furthermore im trying to uninstall them on slave sites, the main site works fine. I believe it was after an update to joomla 3.3.6.

Is there any fix for it? Or is there any way for me to help you fix it?

I tried to uninstall extensions in the slave sites, from their extensions manager and extension manager crashes with the error I posted on the initial question.

The JDatabaseDrive let suppose there is a DB connection error that is not able to get the instance on the DB.

I will try reproducing that.
