Can't uninstall module using the Module GUI

Hello,

 

Just wondered if anybody else has issues with uninstalling pre-packaged modules? I can disactivate them (connectors for Sharepoint etc) but uninstalling just refreshes the page and writes a non-descript error to the log:

Any ideas?

Hello Daniel,

This behavior is definitely not expected. It appears that for some reason the UninstallModule() method is failing but based on the stack trace I cannot determine the reason for this to occur. You can try to either try and uninstall the module from the SystemConfig,config file by changing the following:

to

or , and this is what I would advise you, to submit a support ticket addressing this issue so that me or one of my teammates can further investigate why the uninstall behaves in such a manner on your solution.

Hello Dhananjay,

In the case of dynamic modules, due to a bug in our system they cannot be uninstalled, only deactivated. You can find the bug's status in our FeedBack Portal. Feel free to track its progress there. We will do our best to fix this behavior in our future releases.
