The OssnPhoto Component misses the XML <id>-tag. Might be a matter of luck, that it worked for the admin components list for so long ;)
Thanks for reporting, Julius.
Arsalan applied the fix already.
Due to the many requests in the past for additonal features and components we have decided to develope a premium version. Features like Hashtags, Videos, Polls, Events, Stories, Link Preview, etc included in it.
