I am using DT register 2.7.5c, and I found out that there is a compatibility issue with Jomsocial Events (a function with the same name?) , I get the following error, if I go to the JS Profile of a JS event creator... I tested by deleting all DT components+ Plugins and the error was gone... Did you guys fixed this issue on the latest version?
Thanks

Current version (as of today) is 2.7.7... so your first step should always be to update to the latest version and see if your issue remains. There are no known issues with the latest DT Register + the latest JomSocial. Also, make sure you have the latest versions of our JomSocial plugins. With all current items in place, if an issue remains, submit a ticket so we can check it out.
