Thanks for the quick reply!
Well i copied the default theme, blackcandy and changed the Page.ss and map Layout > Page.ss. Also changed the map name to "xml", as that was the theme. The extension i added "blog" is hard themed, meaning that i changed the template files to reflect the theme (blog didn't have theme files so had to do it this way)
This could be miscommunication, the actual back-end of the admin is fine (/admin). The part that lets you log in, the input fields and such get screwed up because i changed it all to xml. So basically as long as i am logged in its okay but as soon as i have to log in it gets impossible due to the fact that the default them is now xml output wich doesn't give me fields or a way to log in to the admin part.
Basically what i need is for the log in part of the theme to be "normal", i don't really know how to do this (maybe could be changed in the pagecontroller?).
Hope you can help! Thanks for reading.
