My long-running WordPress site suddenly refuses to load and shows an" error.” Nothing has been installed or updated on the plugin side for months, yet our hosting support suggested a plugin conflict might still be the culprit. I need someone who can jump into the backend (cPanel, phpMyAdmin, FTP) and quickly trace the root cause—whether it’s corrupted tables, wp-config credentials, a rogue plugin, or something deeper in MySQL—and get the site fully operational again. Restoring uptime without data loss is the priority, so please be comfortable with WordPress core repair commands, manual plugin deactivation via file manager, and basic database diagnostics. Once you’ve isolated the fault, I’d like a brief summary of what went wrong and any preventative steps I should take to avoid this in the future.
