XDEBUG is what is generating those Orange error messages. That is a seperate product and the documentation can be found here [
xdebug.org]
If that does not yield any help you can always remove XDEBUG and then you will just see the standard PHP error messages.
To disable XDEBUG, edit your php.ini ( using the wampmanager menus ), locate this line ( its at the bottom of the file.
zend_extension = "d:/wamp/bin/php/php5.3.22/zend_ext/php_xdebug-2.2.3-5.3-vc9.dll"
Yours will be have slightly different version number and be in a different php folder but just look for the 'php_xdebug' part.
Then just comment out that line with a # (hash symbol, or pound symbol if you are american)
