I have not had any issues like this before and have not made any changes to the site in awhile.
I’ve tried FireFox and Chrome browsers.
I contacted my host and they said they didn’t see any issues on their end.
Potentially it could be your network. Are you working over a cell network?
No, I have internet through Comcast.
I did try accessing the admin using my phone and it also gave me an error when I tried to log in.
All my other WordPress sites work fine.
I’ve never had this issue before on any network or on any of my other WordPress sites.
I can still access the backend through the WordPress app however…
Only the blog posts though, I cannot access the actual admin area via the app.
I’m not sure if this is worth noting but I also got an email from VaultPress saying they haven’t been able to backup my site since Sept 24.
Hmmm… are you running any security/firewall plugins on your WordPress site?
Also, do you have FTP/SFTP access to the server? Worst case scenario we can disable all plugins and themes this way and start troubleshooting from a barebones WordPress installation.
