I noticed that the discussion-board link appears to redirect to itself. Do you have any plugins redirecting? Have you checked your .htaccess file?
Thanks for taking your time to look on it.
Yes, I checked the htaccess but it does not seem to be the problem (I emptied it and fetched again with same result).
I do have a plugin for redirections - but none of them redirects the discussion-board link to itself. I also deactivated all plugins but the problem did not disappear.
Also - how did you find that the discussion-board link redirects to itself?
I noticed the redirect when I went to the URL... It is Google redirecting you -- look at the URL and message in the attached screenshot. After that appears your page then displays.
I don't know what's happening.
Anyway - the discussion board main page looks good - it returns 200 OK.
But all pages that are linked to it return 404 Not Found
all pages like these below
all of them (500+) that are under the /discussion-board/ - return 404 Not Found
