Sometimes when troubleshooting an issue, SlideShowPro support may ask you to enable debugging in order to see if any error messages are being output. To do this, go to the app/config/core.php file and find this line:
Configure::write('debug', 0);
Change the 0 to a 1, like this:
Configure::write('debug', 1);
Save the file and debugging is now enabled. Once the problem is resolved, you should change the 1 back to a 0.
