Had multiple browser windows open during Moodle 2.5.2 tweaks/troubleshooting and was unable to login: same 'testsession=#' string in URL. Cleared browser cache many times. Long troubleshooting story short: I opened a different browser and got right in. Thereafter, all windows in primary browser were closed (closing the browser), restarted it, and problem was gone. Later, went back to second computer that had been used to test Moodle changes. Earlier browser window was still open and it was exhibiting same 'testsession' problem. Closed the browser, restarted it, and had no further problems.
