Hello @rhinol,
Thank you for reaching out to us!
It might be an issue caused by a plugin or your theme.
I recommend installing this plugin:?https://www.ads-software.com/plugins/health-check/
After you install and activate the above plugin it has a?Troubleshooting mode?which allows you to have a vanilla WordPress session, where all plugins are disabled, and a default theme is used, but?only for your user?– your visitors will still see the normal website.
Go to its troubleshoot mode and?only activate FTG ?and see if it works correctly with a?default WordPress theme (Twenty Nineteen for example) and no other plugins.
Please let me know how it goes and what you find!
All the best,
Beatrice.
