For some reason after working for months when the home screen of my site appears and I have to log in the page just takes me back to the log in again. I have tried this on other computers using Firefox and the problem is repeated. If I change browser I can log in without issue. This problem only started today. I have cleared history and started again and get the same issue but only on Firefox. I am using version 21.0 can you help?

This can be caused by corrupted cookies or cookies that are blocked (check the permissions on the about:permissions page).

Clear the cache and the cookies from websites that cause problems.

"Clear the Cache":

  • Firefox > Preferences > Advanced > Network > Cached Web Content: "Clear Now"

"Remove Cookies" from sites causing problems:

  • Firefox > Preferences > Privacy > Cookies: "Show Cookies"

If clearing cookies doesn't work then it is possible that the cookies.sqlite file that stores the cookies is corrupted.

Rename (or delete) cookies.sqlite (cookies.sqlite.old) and delete other present cookie files like cookies.sqlite-journal in the Firefox profile folder in case the file cookies.sqlite got corrupted.

You can use this button to go to the Firefox profile folder:

  • Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)
