I got it to work. I used TEMPLATEPATH to link up the frontend files on the lines where the warnings referred.
@ghostpool and @vauvarin – did you figure out what was wrong? I have followed the same proceedure and get some warnings referring to class.admin.php
Warning: include() [function.include]: http:// wrapper is disabled in the server configuration by allow_url_include=0 in C:\wamp\www\startup\wp-content\themes\silverpoint\option-tree\classes\class.admin.php on line 372
I got it working. I think it could be a bug in windows 7. The file is downloaded as a .txt file. When I rename it to .xml one empty line is added to the start of the file. I went in and deleted the empty line and it worked as planned.
