Changing skin without accessing admin panel

I am currently changing my skin and i believe the only option is to access the admin panel. But after changing the skin, i cant log in back as the skin doesnt have a log in page. Meaning, i screwed up installing the skin and i didnt like it. Is there any way for me to change my skin like editing the config or something rather than having me to access the admin panel. I try the website/admin but i keep getting please login first. But the thing is i cannot log in at all!

If you access the database, phpvms_settings table (default table name) - you should be able to change the skin name there. Installed skin names are in lib/skins.

Got it work thanks!

goto your website address and after domain type /action.php/login

for example

www.mywebsite.com/action.php/login

then type /admin after logged in
