Ever since I reinstalled Apache recently, my browsers (both Firefox and Opera) show ?reload after the URL in any of my local development sites when the page has been reloaded, as I must do when developing it. If any parameters were being passed through the URL, they are removed and replaced with ?reload. Live sites do not have the issue so it must be something in the default Apache configuration but I see nothing to account for it and it didn't happen before Apache was reinstalled. Any ideas where to look? This is on the latest and fully up-to-date Ubuntu 19.10 system.
