I have a very very strange thing only on some websites. I have restarted the server where many websites are hosted (for maintenance reasons) and after reboot, some websites only have a ? at the end of their URL. At the end of website URL I get index.php? instead of index.php only previously.
Normally URL is https://www.example.com/index.php , but now suddenly is https://www.example.com/index.php?
For info, before restart everything was fine. Nothing has been changed (on nginx or admin tools file maker..nothing)
Do you have an idea why? Do you think admin tools nginx file maker can be the root cause?
I don't understand why and how, as everything was ok before server reboot.
Thanks L.
Root cause : wrong nginx configuration.
