Thanks for the info.
Strato is one of the few hosting comp. that uses Uppercase db names (no renaming). Adding dbasenames will always carry the same Uppercase nameschema.
So e107 will not install because it uses the lowercase (as many other systems also do), so one might say, it is a hoster issue (they made a choice). I do not know if anyone is willing to 'hack'core files for one host, but that is the case here.
The preferred workaround is basically described in the previous posted link (simple explain): install Xampp or any other on your own pc, create a database that ALREADY carries the Strato dbsname (Xampp should allow it)
Install v2 on Xampp.
Copy the created database (export).
Upload all files by ftp to Strato,(delete the install file > so NO install); go to Plesk: open database and IMPORT the copy of your homemade system.
Make sure that your uploaded config php files contains the ACTUAL names for the strato server (it should read AEblabla.. at database.
I can find no quick other solution (well you could switch host).
Dutch easy: Strato accepteert alleen hoofdletters, helaas kun je alleen op hun servers via een omweg, dit geldt helaas niet alleen voor e107, hun andere pre-pakketten zijn waarschijnlijk reeds aangepast,
