Hi and thanks for the great extension.
I'm having a problem with the module CoalaWeb Contact Core.
After upgrading to joomla 3.6.4 i ran the coalaweb contact upgrade from 1.0.7 to 1.0.8 and had an error message.
The module was still working but I couldn't access the backend module configuration.
So I uninstalled and reinstalled the module, but the problem is still there. When I try to access the module configuration I firstly see the normal page but then after one second I get a blank page with a dropdown list on the top left area and I can't do anything then.
