I'm not sure which S5 template you're using. Here are some steps you can check:
1) Check the menu item type of that page, if it's menu item type of com_content for example: single article, category blog, etc...
2) Check whether the template override this com_content or not: [ROOT]/templates/s5_your_default_template/html/com_content/
if there is override folder, try to rename it and check again.
In case that you're using other menu item type, check the same way if template overrides that type and rename.
Again, it's best if you can put your site online and share the login info so I can help. It will save time for both of us.
