You have a phpBB3 board, but you originally posted in the phpBB2 Translations forum.
I have just moved your post into the phpBB3 Support forum.
However, as already stated, you are running on a "free forum host". You need to ask them for support. ("Them" = forumotion.net. Their support pages are at http://help.forumotion.com/
which is shown at the foot of every page on your board.)
Also note, they have modified the style to remove the full phpBB copyright, which also disqualifies you from support here, as per rule4j
