'Advertising' link not showing up on my computer

[dougmcc1]

I'm building a search engine friendly directory of categories and subcategories using PHP and MySQL. The link is in my profile. All of the category and subcategory names are pulled from a database and each one links to a directory.

All the categories are listed on one page and each one links to a new directory that lists all the subcategories for that category.

For some reason, when I create the 'advertising' category, it doesn't show up on the categories page. There's a blank space where the link is suppose to be. The tag for the link doesn't appear in the source code either.

I saved the source code on my computer and manually added the Advertising link and saved the page as a static page, uploaded it to my website and found it had the same effect - the Advertising link didn't show up on the page or in the source code for the static page.

I pulled up the dynamic page on a computer at school and the linked showed up. It also shows up on a different computer at home but not on my main computer. Both home computers share the same cable broadband modem.

Also, categories named "Ad", "Ads", or "Advertisements" don't show up either.

Any ideas? Thanks.

Do you use Norton Internet Security?

Yeah and when I disabled it the Advertising link showed up.

Man I have never seen any software that causes more problems than Norton Internet Security.
