@ Ruud & Erpe
Sorry for the long wait. My wife gave birth to our son so that had a bigger priority

But anyway... Finally the movement from A to B worked.
What I did:
- Installed a new (same version) WB on server B
- downloaded the config.php to a place on your pc from server B
- downloaded ALL the files from server A
**- export the DB from server A
- delete the DB from server B
- import the DB that you created from server A into server B
- upload all these files to server B
- upload the config.php file to server B again
And your done.
** The problem was that the files created by WB were not downloadable. Therefore I had to CHMOD every single file to 777. That took days because this client had over a thousand pages. And webadmin.php isn't able to CHMOD multiple files at the same time.
So...I searched the Internet for a program that could do this job and...I found one!
Here you can download it and upload it in the root of your server. After that there are lots of options but the biggest one is: the possibility to CHMOD hundreds of files
at the same time!!With this single file this whole operation is peanuts. Good luck and thnq for your input!
