CPanel and WordPress Not Working – API 500 Error & No Website Access

CPanel and WordPress Not Working – API 500 Error & No Website Access

I am experiencing an issue with my cPanel. It was working fine, but sometimes it stopped due to an IP block. However, this time, the issue is different.

None of my websites are loading.

When I try to access WordPress via cPanel, it does not respond.

I am getting an API 500 error.

I cannot create new subdomains.

I have 15 websites on the same hosting, and all of them are down.

Additional Details:

Hosting plan: Premium

Storage: Sufficient available

What could be the possible reason for this issue, and how can I resolve it? Any guidance would be appreciated
