WordPress include destroying osCommerce session data

Ok, so I’m completely lost now.

I have included wordpress into my osCommerce site.

I know what you are going to say, use the plugin that does this for you. I tried, our osCommerce is heavily modified and most plugins don’t work with it. 3yrs worth of mods.

Basically, when wp-blog-header.php is included it destroys some of the osCommerce session data. This has nothing to do with the mods, I have included the latest stock oscommerce application_top.php with wp-blog-header.php and have the same issues. It’s wordpress destroying the session data.

I have commented out wp_unregister_GLOBALS(), used the filter options in it with little success. Some things were fixed, others were not. I am now down to $_SESSION[‘language’] getting unset, and set as either WP or en. In wordpress it should be english. I’m not sure where WP is coming from, but I know en is wordpress defaulting to the browser language.

How can I stop wordpress from taking over the global and session data?

Any help would be greatly appreciated!

If this has been resolved, please post me a link and close the thread! I have been searching for a week to resolve this, the things I found and tried are listed above!
