@patrickposner – so today I tried it by setting all URLs with “/” at the end. I set the domain URL in the wp-config with “/”, I changed permalinks with “/” at the end and I added the following snippet to the .htaccess
@patrickposner thanks for your answer and the possible reason for this. In my browser I think every website is shown with the trailing slash at the end of the URL (maybe the browser adds it automaitcally?). Because in all my wordpress websites in Settings->General->WordPress Address the URL is shown without trailing slash. When I add one, it will be removed automatically.
So what I did now so far: I tried to remove the trailing slash by changing the permalink settings in wordpress (remove the last trailing slash) and I added some code to the .htaccess for removing the trailing slash. But I still get the same index.html.
Today I will try to add the trailing slash via .htaccess and permalink settings in WordPress. But I reckon it will not help…
