The question is, do you actually get anything at all or do you just get a white screen? Or does the status bar continually act like it is trying to load for the whole time?

with
PHP Syntax (Toggle Plain Text) 
  1. error_reporting(0);
if memory serves me correctly, this command actually turns off all levels of error reporting.
Try commenting that out and then going to your page, you may see where your errors are.

When working with PHP, sometimes it is a good idea to to view the source of the page which is rendered (the outputted html, xhtml or xml). If you see any code there at all, you could look through it to see if perhaps there are some tag close issues or whatever.
I could be off base with the above function, but I think I remember this being the case.

Hi dami,

sagedavis is right, error_reporting(0) turns off all error reports, therefore you will not get any errors on that page, instead replace that line with this:

ini_set('error_reporting', E_ALL);

Then load the page, you should see errors then
Technology is just a tool. In terms of getting the kids working together and motivating them, the teacher is the most important.

Thanks, I got 2 errors. I'm not too sure where the error is because it's not making any sense. The errors are
Notice: Only variable references should be returned by reference in C:\xampp\htdocs\capat\library\classes\class_engcis.php on line 9

Parse error: syntax error, unexpected ';', expecting T_FUNCTION in C:\xampp\htdocs\capat\include\classes\class_ui2.php on line 336

Notices can be ignored. Notices can be turned off by changing the error_reporting setting in your php.ini.
Anyway, as ryan_vietnow has already mentioned, there are 2 ?>. And then, the } for the class UI is missing.
Ignorance is definitely not bliss!
