We’ve made a small bug fix to our SocialEngine Integration Kit for AVChat that fixes the following error:
Fatal error: require_once() [function.require]: Failed opening required 'Videochat/Mobile_Detect.php' (include_path='/home/avchat/public_html/se/application/libraries:/home/avchat/public_html/se/application/libraries/PEAR:.') in /home/avchat/public_html/se/application/modules/Avchat3/views/scripts/index/index.tpl on line 57
The new build number is 3135 and can be downloaded from your private client area.
You can also solve the above issue by editing application/modules/Avchat3/views/scripts/index/index.tpl and replacing Videconference with videconference (lowercase v).
