I was doing some work in phpmyadmin earlier and a bit of messing about, I got this error: “phpMyAdmin – Error. Cannot start session without errors, please check errors given in your PHP and/or webserver log file and configure your PHP installation properly.”
I tried all allsorts, I even rebooted the server but it still kept showing. Fearing the worst I did a bit of googling and came across this article. If you scroll to the bottom the last entry which reads “PHPmyAdmin can also get confused with cookies after a crash, try emptying the cache”. So, I did this and hey presto – It worked. Awesome.
