Hello divinepm,
Some things we need to try,
- Create a backup of your theme and then delete it from your theme folder before downloading a fresh copy of inFocus 1.6 to replace it. If the arrow disappears then it was most likely due to some kind of customization.
- Deactivate all plugins to see if the arrow disappears. If it is gone then reactivate them one by one to see which one was causing the problem.
It seems to be appearing on every one of your template files so it is most likely a plugin / script that is inserting it.
