Michael,

in the meantime I have a reply from my hosting provider: They didn’t find any errors in their server configuration.

I checked my php_error.log and found no entries.

I ran your “test script version 4” and – as far as I can judge it – everything seems to be fine. I have sent you a screenshot of the results of your test script by email.

If you want me to run a different script I’ll do so of you provide me with it.

Thank you
