The "OSTeam Testimonial" module works on the front end but i can't edit it.If i click the module i get the error "behavior::modal not found." on a bare screen that doesn't include the usual Joomla GUI. Under the error there is a button that returns me to Joomla Dashboard. When i then look at the module it has a lock icon next to it which i can get rid of by selecting the module and clicking Actions/Check in.
The template page that describes how it's modules were made doesn't include an explanation of the "OSTeam Testimonial" module.I'd like to delete the module and recreate it with my own settings by i don't know how it was created.
