A site can remember an outdated setting or keep sending you back to a broken page. If the problem is confined to one site, first check its address. Removing its cookies may sign you out and clear saved preferences. Finish or save any draft work on that site before you start.
Find the exact site in Chrome settings
Open Settings → Privacy and security → Third-party cookies → See all site data and permissions. Search for the site and compare the result with the address you noted. Select the delete control next to that entry and confirm. If there are similar names, check the domain before you confirm.
Reopen the affected page
Open the site again. Sign in if needed, then repeat the action that was failing. For example, check whether changing the display language now stays in effect after a reload. If the failure returns, note the exact page and what you tried so you can report it to the site.
