Last night an arabian guy hacked the message board. Fortunately, I had the latest backup of the database and restored it.
To prevent any future hacker attack, I upgraded the message board to the latest stable release of phpBB forum and its MODs. In addition, I added Favorites MOD to the message board, so that you can have a list of your favorite topics.
However, I did a big mistake and before upgrading I forgot to make a back up of users' uploaded files and avaters.
Therefore, the previous avatars and attached files are lost. I contacted my host provider and I hope they restore their backup. 
I apologize for any inconvenience that my mistake may cause.
Greetings
