writing a new plugin

Hi friends,

I am writing a new plugin for creation of the post from a remote url. I was testing it simultaneously. I was in the middle of the tutorial i was following on internet n suddenly the page appear as blank. Now when i check the url of my site locally it appears blank. Since it doesnt throw any error as such am wondering wht can be the matter with wordpress.

Any word of help is appreciated. Please help.

Regrds,
