Hi @iamdaniells
I’m sorry to hear that you are experiencing this issue.
Could you disable and enable Hummingbird plugin once again and see if that helps after refresh?
Also would you please run a conflict test? Please deactivate all plugins except Hummingbird and check if the problem is gone. If so, then enable all plugins one by one and find which one is having a conflict. If there is no positive result, switch to default WordPress theme like 2019 and see if it works.
Before this test, I recommend full site backup or run this test on a staging site.
Kind Regards,
Kris
