Thanks for your wonderful support so far!
Now I'm stuck in a kind of loop here.
Importing contacts from my xml file works only in parts.
After 25 items (some seconds) I get a 500 server error. I treid different values, but after 30 contacts max the system gives a 500.
I'm testing and developing on my local machine so I have access to the log files. But they don't show anything. In fact no error files are created.
So I thought I'd move to an online test installation, just to try out. Therefor I wanted to export / backup my import templates. Unfortunately this creates an error, too:
So I guess this is a good start to ask for help again.
How can we proceed this.
Regards!
