Custom webapp: 302 Found error

I have a weird error message after I upgraded a custom webapp, and I wonder if it has to do with Yunohost and its Nginx configuration or not and if it possible to fix.

I upgraded the wonderful Wikindx - a simple oldschool php mysql app and when I go to the frontpage I see

before further below I am able to see the usual front page content.

This happens only on the front page. The other pages with names as do not display the 302 error.

There are no error message in the log apart from this warning

nginx: [warn] could not build optimal proxy_headers_hash, you should increase either proxy_headers_hash_max_size: 512 or proxy_headers_hash_bucket_size: 64; ignoring proxy_headers_hash_bucket_size

Any ideas? Thanks!

What version of Yunohost are you running?

Do you see any errors in:

Thanks for your reply. I run the latest H version. No error messages in these files. It might be no YH issue then?
