widgets admin has gone screwy

I installed this plugin and it took my site offline so I decided to remove and delete it. Unfortunately, since then, I havent been able to get into my widgets in admin! When I hover over the link it’s supposed to go to https://example.com/wp-admin/widget.php, but it forwards to: https://example.com/~4258129.4832578/htdocs/~4258129.4832578/htdocs/~4258129.4832578/htdocs/~4258129.4832578/htdocs/~4258129.4832578/htdocs/~4258129.4832578/htdocs/~4258129.4832578/htdocs/~4258129.4832578/htdocs/~4258129.4832578/htdocs/~4258129.4832578/htdocs/~4258129.4832578/htdocs/~4258129.4832578/htdocs/~4258129.4832578/htdocs/~4258129.4832578/htdocs/~4258129.4832578/htdocs/~4258129.4832578/htdocs/~4258129.4832578/htdocs/~4258129.4832578/htdocs/~4258129.4832578/htdocs/~4258129.4832578/htdocs/wp-admin/widgets.php

I removed the redirect code in the htaccess file, and I double checked to see if it was still in the active plugins table in wp_options in phpMyadmin, I have tried disabling all plugins, and I am still getting this error.

This is a project that needs to be completed ASAP. Please help! I am not sure what to do at this point!
