I used the Compojoom installer and successfully installed it. The attachment shows the message I received as "Error installing extension parsererror" when I used the installer. When I used the Joomla installer I was able to get to the migration screen but it went no where and ran overnight. My server supports curl 7.54.0, too. Any help would be appreciated. Thanks!

Earlier issue submission:

The dialog box asked not to leave the page but it's been running with no progress bar movement. I have Events (97) and Bookings(1042 bookings). How long does it usually take to finish the migration. Also, I'm using Firefox as my browser. I've also tried Goggle and Safari browsers but I'm not getting a progress bar to indicate the migration has complete. I did successfully installed the compojoom installer.

Any help would be appreciated. Thanks!
