Snapshot plugin messed appearance of my multisite

Hello,

I used a plugin called Snapshot by WPMUdev.org to copy a single site to my multisite as a subsite. Even though I followed the instructions, this did not work out. Now my multisite appearance is a combination of the single site and the multisite!

Since I did know I was not supposed to, I copied over the WPconfig.php file and the htaccess file. I had copy another single site this same way and it did not change the appearance of my multisite.

How can I fix this? I don’t think copying over the WPConfig.php and htaccess file would mess up the appearance of the multisite? The theme area is in the WPContent folder.

Does anybody know how this can be fixed!!

Thanks!
Janet
