blank web page

This looks like a common problem but i wonder why you don't have an FAQ on this...i was changing the theme of my site and then it disappeared from the web when i tried to view it.
i just get a blank page and i tried loggin in to wp admin but the same blank page..
i have submitted a icket but reading through the help questions it seems it a very very typical problem?

Hi Gregory.<div><br /></div><div>While this is a common symptom for many different WordPress issues, it can be caused by a number of different things.</div><div><br /></div><div>Most common cause is a plugin conflict, which requires disabling all plugins via FTP to regain access to wp-admin and troubleshooting from there. You can see the exact procedure here: <a href="http://codex.wordpress.org/FAQ_Troubleshooting#How_to_deactivate_all_plugins_when_not_able_to_access_the_administrative_menus.3F">http://codex.wordpress.org/FAQ_Troubleshooting#How_to_deactivate_all_plugins_when_not_able_to_access_the_administrative_menus.3F</a></div><div><br /></div><div>The second most common cause is a theme issue. You can rule this out easily using the WPDirect Theme Gallery. Locate the WordPress Default Theme in the gallery and use the "Install to Existing Website" link to install to the site in question, and the default theme will be activated on the site.</div><div><br /></div><div>I have looked at your site and addressed the issue in the ticket you opened.</div><div><br /></div><div>If you need further help, please reply to that ticket, as all replies to this ticket are visible on the question board.<br /><br />Thanks.</div><br /><br />Brian Zeligson<br /> Customer Support Representative<br /> WPDirect.com<br />
