Can't find where to edit/remove "about us" link..

im currently running version 1.3.9h. Toying with idea of upgrading if needed but id prefer to not fix something that isn't broken. If you click on my
"about us" link it says to go to admin-define pages editor, however there is no option in the drop down to edit it.. Any help with this would be greatly appreciated..

Do you see a file in your directory:
/includes/languages/english/html_includes/

Do you see a file in your directory:
/includes/languages/english/html_includes/your_template_dir/

that looks related to the about_us? :unsure:

Under html_includes there is no about_us.php file. I checked the main_page.php but it just tells me to go to define pages editor which is a dead end or to go to my_template folder and open the main_page.php from there, however no such file exists.. in that location however an about_us.php file does exist but when i open it in my code editor all i get is :

i tried adding some content here but the content doesn't show up on the page and the page doubles in size..

turns out the define_about_us.php file was missing from the template im using.. downloaded a similar template to ftp'd the file over to the proper location.. problem solved!
