When attempting to go to the administrator pages, it asks me to validate my credentials. Once I verify my credentials, I am redirected back to the login validation page instead of the to the administrator pages. I have tried clearing my cache/restarting browser, but to no avail. We are currently using v7.12.3. This has been an issue in the past (in previous versions as well), but I was usually able to brunt force my way through; brunt force no longer works.
