Cannot index oscommerce site

[izzyshams]

I have site running creloaded backend and would like to index it using the Zoom Search engine sotware, but for some reason I can't index it. The site is coded in php, so the index is index.php

The log file says the following (I have removed my site name to prevent google indexing):

I've used other website search programs and they spidered the site fine. I really like the features of Zoom Search though and hopefully this won't be a deal breaker for me. Any suggestions?

The key line in the log is this one,
Could not download file: http://www.*******.com/index.php (Internal server error)

This means that the server failed or refused to serve up the page.

If you look at the page using IE, you'll probalby see the same HTTP Error 500 Internal server error.

Just to double check, I went to the osCommerce web site and indexed a few of their showcased web sites, without any problem.

The site works fine in IE as well as other browsers. Although I figured out what the problem was. It was that I had gzip compression enabled for my website. Once I turned that off, I was able to successfully index my site.
Thanks Wren!
