Hai Miguel,
I am sorry for the delay of this reply.
Regarding your issue, I already update EasySocial new version 1.4.4 for you.Can you give it a check now, it seems work fine now.
I notice in my installation that you php Passthru is disabled, in EasySocial 1.4.4 come with video feature, that you user can upload video to you site, if you want to have this feature in EasySocial you have to consult you server provider to enabled this Php Passthru.
if you server provider have enabled this feature you can choose to use or not just go At EasySocial>settings>video>enable video ( yes/no)
