blank screen on log in & log out

[masyomo]

Hi - am using joomla 1.0.10, bridge 1.14

site is www.yomotraining.com

When logging in and out users get sent to a blank screen. If they refresh they have actually been logged in or logged out

On the othergand if they enter their password incirrectly it does go to the right screen (the incorrect password one I mean). So its only when loggin in and out that it happens.

I've tried reinstalling the brifge but its still there.

Theres a test account which is username: test and password: tester if that helps.

I've checked all the settings and added the extra code (the 1.09 compatibility thing)

best add to that that it seems ok on internet explorer

the problems with firefox
