Currently, from the frontpage of orionfeedback, there is no option to flag a post.
Additionally, from search eg https://orionfeedback.org/t/desktop?q=sponsorblock
or by clicking something from the sidebar like https://orionfeedback.org/t/suggestions
there is a flag option, but clicking it causes an error, freezing the entire page.
Not sure why flagging a post isn't properly working, considering that all the other options work just fine.
