Update....
WEBERP is running
Problem was indeed rights and some weired behavior of the webhost.
I followed the install (yt) video and after reading the manual I discovered the DB path config.php had to be set to msql not msqli.
Gave him a call and we walked trough it.
Problem
server rights set correctly, he couldn't tel me why but needed reconfig. after that I could delete files on de web-server.
Server is 'anybody' thus better secured. he explained it and I understood.
After that he created a new DB with the name wep
ERP not weberp. somehow the script wants/looks for a DB with that name (_webERP)
He is a pro and if he had some spare time he would look in to it. His first reaction was quite pleasant about the software so maybe another antousiast.
I am
after spending some time looking things threw.
