Just Installed WP Super Cache and getting an error message

Hi,

I’m a newbie to WordPress Caching. I just installed WP Super Cache, taking care to configure it to the recommended settings in “details”. My main website is at http://www.pjmconsult.com and the WordPress Blog homepage is at http://www.pjmconsult.com/index.php

When I test the cache here are the results I get:

Test your cached website by clicking the test button below.

Fetching http://www.pjmconsult.com/index.php/ to prime cache: OK

Fetching first copy of http://www.pjmconsult.com/index.php/: OK (1.html)

Fetching second copy of http://www.pjmconsult.com/index.php/: OK (2.html)

The pages do not match! Timestamps differ or were not found!

I looked at the two pages and they look the same to me–I didn’t see any errors. But I really don’t know what I’m looking for. I also turned debug mode on just prior to writing this–but again, not sure what I’m looking for. Can someone help me out? I’d like to speed up my site, but don’t want to cause problems either. Your help is greatly appreciated.

Thanks,

Phil
