Integration problem - can't change month

[indiza]

I've gone through the install process, and have attempted to integrate my calendar into my own site. I've read through the Integration instructions, and have followed the steps (as far as I can see) to the letter... but, when I actually go to view the page, the calendar is stuck on 'October'.
Clicking the 'backwards' arrow does nothing, clicking the 'forward' arrow changes the URL to 'mo=11', but what I'm seeing stays the same.
Just to see what would happen, I changed it to display both the normal mode and the blog mode... The list of events underneath the calendar seems to be behaving normally (displaying today's events), but there is no change with the actual calendar.

I'm been staring at this for quite a while, and I really can't see where I've gone wrong... All the paths look correct (my calendar.php file is within a folder called 'calendar'), and I've essentially copy/pasted all the code from the integration section of the instructions... Is it possible that the unrelated PHP coding on the site is interfering somehow?

The eventcalendar.php file is attached. Any help would be greatly appreciated!

We'd need a link to your site... With just the source, we can't see how it behaves.

....The problem seems to have spontaneously sorted itself out. Thanks, though. I'll post the link if I have any other problems.

No, I lied. The problem only appears when events are actually added to the database.

You will have to log in with the username and password 'test'.

Works A-1 from here... Firefox on Linux.

Eh... I guess it's just not liking Opera then. Thanks!
