But how I can open that in Excel?
I expected a download for a CSV File.

I tried it, disabled the HIKA User Sync, but I had the same errors.
And in my opinion the Export i not what I expect: I want a CSV File download, I think a standard for Export in such tols.
Thank you

I'm sorry, but the file is now renamed.
You can see thet in the attached screen shot:

Then I cleared all cache in Joomla. The cache in Joomla settings is also disabled.

But the errors on the order export page are the same.
Do I have to rename also the hikashopgeolocation.php file?
Where we need the function of this file?

Now it's OK, moving Joomla to the root folder from the /test/ folder.
It was a missconfiguration in .htacess
