For some reason upon attempting to install the latest version of JoomSEF into a new, fresh installation of Joomla 1.5.7 the JoomSEF install seems to crash with a blank white page and the two lonely words: Invalid Token at the top of the page.

I attempted the installation again and the same thing happens. Artio is the first and only component I have attempted to install so far.

I have pasted the vital information below that was requested in the readme post:

Database Version: 5.0.67-log
Database Collation: utf8_general_ci
PHP Version: 4.3.11
Web Server: Apache
Web Server to PHP interface: cgi-fcgi
Joomla! Version: Joomla! 1.5.7 Production/Stable [ Wovusani ] 9-September-2008 23:00 GMT

Is there a simple reason for this error message?

Thanks!

Very strange. I went ahead and installed the other components into the system, went back and then tried to install JoomSEF again and this time it worked... Wierd.

Sorry for the unnecessary post.
