all of a sudden, my permalink structure %postname% ist not working anymore.
Why it’s not working?
Have a read of Using_Permalinks try a custom permalink structure again. If clearing your Permalinks does not alleviate the issue, this could be attributed to anything from a web server configuration to a bad WordPress install.
I don’t know, why it is not working anymore because I haven’t changed anything the last time on the problematic website.
Yes, I have read that and changed permalink structure to custom as you said, but unfortunately without success. Absolutely no other structure is working anymore than ?page_id=X
Every other website on our server is working fine though.
@ringostar77 did you fix this afterwards? I have been experiencing this same issue since yesterday. When we try to go to http://domain.tld/page the URL is being changed to http://domain.tld/?page adding a ? in the URL and not loading the correct page. I checked the permalinks section (/wp-admin/options-permalink.php) in the settings and it is set to ‘Post name’. What else could be adding the ? to the URL?
@qroberts I fixed it. There was a misconfiguration on some domains in plesk. I was using nginx and with some custom redirect rules. These rules were causing the issue :/
@ringostar77 Hi can you explain what you did? I have similar issue on a plesk environment and i’m new to this. Thank you
@organu @ringostar77 we are also using Plesk. I checked our .htaccess files and they look good for WordPress. I also disabled every Plugin and the question mark is still getting prefixed to our URL’s.
Our permalink settings (wp-admin/options-permalink.php) are set to use Post name. If I change this to Plain the website works as the question mark is needed anyways for the URL ?p=123 or ?=page_id=123 but with Plain you do not use question marks.
In Plesk when I go to the section where the domain is, under “Apache & nginx Settings”, I have the following settings:
MIME types: default
Handlers: Default
Deny access to the site: Default
Index files: Default
Expires: Default
Additional Headers: Default
Restrict the ability to follow symbolic links: not enabled
Proxy mode: Enabled
Smart static file processing: Enabled
Serve static files directly by nginx: not enabled
Enable nginx caching: not enabled
I just want to bring up this to help you guys how to fix it.
You don’t need to restore your web files or database. Also no need to workaround related permalinks settings. This issue only related for those who use Plesk control panel only.
Go to your control panel, on “Apache & nginx Settings” section, make sure everything revert back to default.
On “Hosting Settings” section, under “Web scripting and statistics” section take a look PHP version of your website and run PHP as xxxx. Change run PHP as xxx from previous one to another. ie. I have previously FastCGI application serverd by Apache. Now change it to another else, ie. FPM application served by nginx.
Done.
