How do I safely disable a broken plugin via FTP when I can’t access my dashboard?

When the backend is completely locked, you override the dashboard by using an FTP browser manager to rename the individual folder directory of the broken component, forcing WordPress to safely skip it.

“This is a safe, well-known workaround, renaming the plugin’s folder over FTP so WordPress simply skips it on load. I’ll get you back into your dashboard within 24 hours for $99.”
