Hello,

I'm currently experiencing problems with my WAMP server installation. I've been using wamp for past 4 years, and have had no problems at all during this time. Recently I noticed that I can't log in PHPMyadmin or SQLbudyy at all.

Please do note, I haven't made any configuration changes during these past 4 years, this just happened one day.

When trying to log in to SQLBuddy I get this error - There was a problem logging you in.
When trying to log in to phpMyAdmin I get this error - #1045 Cannot log in to the MySQL server.

All the sites work with no problems.
I actually just wanted to clean up my wamps "www" directory, backup sites, uninstall wamp (2.4) and install the newer version.

I've been searching internet for quite some time, trying to find what could have caused this problem, mostly errors like this are due to misconfiguration in configuration files, but I haven't even touched those.
