Hi dominic ,
I just recognized, I didn't copy the database, so you're still using the original database.
Do you want me to copy the database for the subdomain as well?
In addition, you'll be redirected to the Main page, each time you call dbg.beim-maler.de, so to test everything, you should call a sub-page like dbg.beim-maler.de/preise
Sorry, I'm still a beginner but I'll do my best.
Thx, Johnny
