Not getting Errors...

[eluser]kb1ibh[/eluser]
Hello all, having some trouble i hope you can help with...

im working in a development environment and I'm constantly running into small syntax errors (missing ;'s, stuff like that) and whenever there is an error, rather than printing a message giving me a message, or even a line/filename, it doesn't display anything. just a blank page. its really slowing me down, and im looking to find a way to re-enable this error reporting, but havent found it yet, can someone point me in the right direction?
thanks
