Thank Ray. I did this but same result. I noticed that the "styler.php" file was being called from /store/webassist/plugins/styler/styler.php but that file was actually only inside /store/install/webassist/plugins/styler/styler.php Actually, there was not any webassist folder in store/, only in store/install/ so I copied it and placed it inside store/ All that said, I still am getting the same error.
