I am having a problem with my admin panel after installing STS. I have seen this referenced here before and when I posted it in the regular installation forums I was sent here for help. Any help would be very much appreciated.
I copied all of the files STS installation instructions told me about, and went back to my admin panel and this is what happened.
Warning: require(includes/classes/navigation_history.php) [function.require]: failed to open stream: No such file or directory in C:\xampp\htdocs\catalog\admin\includes\application_top.php on line 128
Fatal error: require() [function.require]: Failed opening required 'includes/classes/navigation_history.php' (include_path='.;\xampp\php\PEAR') in C:\xampp\htdocs\catalog\admin\includes\application_top.php on line 128
Thanks in Advance!
