Extremely new – I'm trying to reinstall WordPress with ssh on nfh.

Hi all!

I appreciate any help here as I’m terribly new at this. I’ve just learned the command line which has been somewhat helpful, but I’m now quite stuck. I’ve been trying to do everything via Terminal.

Issue: Anything I do on WP-CLI is giving me “Fatal Error: Fatal error: Class ‘WP_Widget’ not found in /home/public/wp-includes/widgets/class-wp-widget-pages.php on line 17”

What I’ve done so far:
I’ve disabled all plugins on my site. I couldn’t figure out how to do this from ssh, so I did it on the WordPress panel.

This didn’t help, so after more searching online, I saw that a manual reinstall should help. The downside is…I have no idea how to do that. I downloaded the zip file, so the next step should be getting it onto the ssh (I’m using nearlyfreehosting).

I tried wp core download and it tells me it already exists.

Again, any help would be very much appreciated. I’m doing my best to do more research on how do to this in baby steps, considering I now can’t do anything on ssh.
