Sitemap mod installation problem

[cector]

I am using SMF 2.0 RC3 with kokpit theme. When I was install sitemap_2-1-2 in my forum I got the below error:

"Error in Package Installation
At least one error was encountered during a test installation of this package. It is strongly recommended that you do not continue with installation unless you know what you are doing, and have made a backup very recently. This error may be caused by a conflict between the package you're trying to install and another package you have already installed, an error in the package, a package which requires another package that you don't have installed yet, or a package designed for another version of SMF.

Those errors are caused by other mods having already modifed the file.

Check the parser, on the mod's download page.

That'll tell you what edits have to be made.

You need to make the edit to Admin.php, manually.
