Error in 4.5.2 after uninstalling eCart 5.0
After realizing that eCart 5 only supports PHP, I uninstalled it and reinstalled eCart 4.5.2 because I'm working on a few older sites i created using ASP.
Now when I try to use certain eCart features (i.e. inserting an add to cart button) I get a pop-up telling me: "ecart is only available '.php' files in PHP websites"
I uninstalled the extension, restarted, and manually deleted any files left on the system associated with eCart. After reinstalling version 4.5.2, I'm still getting this error.
