Cpanel Redirects
Design and Skin Customization
Assuming you have now removed your redirect from htaccess...
Is /oilfield-store a part of Jamroom or something else? Is it a directory? Is it a file? Is it a jrPage item? Or a Sitebuilder url?
If so, try deleting it (or temporarily renaming it).
The url mapper works for
non-existant urls.
Does the url mapper work for you for a different url? Give that a try as well.
