You are a real Gent, thanks a lot!

But I just backed up to my old files - so the forum is running.

I am just playing around with the Birthday Mod, as soon as this one running, I will use your file to get the Last Visit Mod to run!

Once more thanks a bunch - you are really a great supporter!

If you ever visit Vienna let me know, there are at least a couple of beers on me!

[extralarge]

EDIT: the birthday mod is working again, but when uploading the language/lang_german/lang_main.php I still get this error:

Parse error: parse error, unexpected T_STRING in /home/www/web355/html/phpBB2/language/lang_german/lang_main.php on line 1088


@ acoolwelshbloke


Could you please help me once more?

Thanks[/img]

[acoolwelshbloke]

You have an error in your lang file!

And second of all it is a german language file yes?

I don't speak german i'm in the uk so sorry I am unable to help you with this.

I sujest you post whatever is on line 1088 of that file and see what other german speaking members have to say.

[extralarge]

Never mind, found it, in the german lang_main there was a ' missing, now it is working great!

Thanks a lot for all your help!
