I have this error warning message. *Warning*: Cannot modify header information - headers already sent by (output started at /home/dubai/public_html/store/admin/includes/classes/[url removed, login to view]) in */home/dubai/public_html/store/admin/includes/functions/[url removed, login to view]* on line *55
*The error message occurs when I add a new category or subcategory. The category will still create itself but that error message displays each time. We expect you to fix this error message and for the site to be in complete working order without any error messages or warning messages.
There are many contributions installed on this oscommerce site and I expect for them all to remain working properly. I want a professional who has experience in fixing this error message. I will not be accepting the lowest bid, so give a fair price for the work as described. Happy bidding.
