I have swapped themes and the issue still persists. i don't know what permission or bug this could be so I don't even know how to trpoubleshoot this
When you say you "swapped themes" you mean you changed to default? Your images are not default themes.
For bug or other troubleshooting, it might be helpful for a URL, and if necessary, an account to log in for testing.
What version MyBB?
Have you enabled error logging? And does anything show up there?
Quoting is evaluated in class_parser. Have you made mods there?
What does AdminCP / Tools & Maintenance / File Verification show?
And did it work recently, then stopped? What did you change?
A new plugin? A new theme?
All of these are troubleshooting steps that help describe what you have done to isolate the problem.
Without details, it's more difficult to provide an answer.
Send me a URL and test account. I will look.
AdminCP / Configuration / Server and Optimization Options
Use Error Handling -- On
Error Logging Medium -- Log errors
Error Type Medium -- Warnings and errors (gives immediate on-screen feedback that something is not right)
If you use Hide Errors and Warnings, they are not displayed onscreen, but are logged.
Error Logging location -- ./error.log
You can then review the error.log at yourdomain/forum/error.log
