I have a problem. After first installing the contribution Ultimate SEO URLs I checked everything and everything was working 100%. Then I installed this contribution and it works like a charm in the shop that the customers see (thanks Ken for your great contribution!). The problem comes when I'm trying to login to the Admin area, I only get an error now stating: Warning: include_once(includes/classes/seo.class.php) [function.include-once]: failed to open stream: No such file or directory in /home/stars/domains/mydomain.com/public_html/admin/includes/functions/html_output.php on line 22 Warning: include_once() [function.include]: Failed opening 'includes/classes/seo.class.php' for inclusion (include_path='.:/usr/local/lib/php') in /home/stars/domains/mydomain.com/public_html/admin/includes/functions/html_output.php on line 22 Fatal error: Class 'SEO_URL' not found in /home/stars/domains/mydomain.com/public_html/admin/includes/functions/html_output.php on line 25 Any idea of what could be wrong? I have checked everything and the file that it is asking for (seo.class.php) is in the correct folder, and I have also uploaded it again to be sure it is no problem with that. Please help me, thanks!

Ok! Is Ultimate SEO URLs compatible with "Header tags for novices": http://www.oscommerce.com/community/contributions,4822 Everything seems to work fine in the shop after installing both, but I can't access the Admin area anymore after first installing "Header tags for novices" and now "Ultimate SEO URLs". When trying to login to the Admin-area in the shop it stops and I only recieve this error: Warning: include_once(includes/classes/seo.class.php) [function.include-once]: failed to open stream: No such file or directory in /home/stars/domains/mydomain.com/public_html/admin/includes/functions/html_output.php on line 22 Warning: include_once() [function.include]: Failed opening 'includes/classes/seo.class.php' for inclusion (include_path='.:/usr/local/lib/php') in /home/stars/domains/mydomain.com/public_html/admin/includes/functions/html_output.php on line 22 Fatal error: Class 'SEO_URL' not found in /home/stars/domains/mydomain.com/public_html/admin/includes/functions/html_output.php on line 25

Thanks! I found it now, it was the htaccess-file included in the Ultimate SEO URL-package that had the register-globals value turned off. As soon as I enabled register-globals again in htaccess all stock reappeared. Is it really needed to have registerglobals on for OSC to work correctly?

I have just installed this great addon to OSC and everything works as a charm except that for every product it displays is says that it is out of stock. I have from 1 to 30 pieces in stock on every product but it doesn't matter, all products now shows "Out of stock" in product information page since I installed this addon. Any ideas what could be wrong? Many thanks in advance! ;)
