Plugin disabled and uninstalled, Facebook not allowing me to share because of it

I get an error on Facebook when trying to share my site, even in messenger:

sarahkcarey.com/

its saying the following:

You can’t post this because it has a blocked link
The content you’re trying to share includes a link that our security systems detected to be unsafe:

https://sarahkcarey.com?password-protected=login&redirect_to=http%3a//sarahkcarey.com

Please remove this link to continue.
If you think you’re seeing this by mistake, please let us know.

We have since disabled the password requirement, and uninstalled the plugin, however facebook still blocks this. Could this be a cache issue, or would there be residual files left from the plugin that could trigger this?
