Fix WordPress Login & 503 Errors

I urgently need help getting my WordPress store back on its feet. Since updating a specific plugin (I’ll share the exact name as soon as we start), I can no longer reach wp-admin, several pages throw 503 Service Unavailable, and the “Top-Selling Products” section has vanished from the front end.

I still have full access to cPanel, File Manager, phpMyAdmin, and error logs, so you’ll have the tools you need to dig into PHP, .htaccess, or the database without delay.

Here’s what a successful hand-off looks like:
• wp-admin loads normally with no redirects or white screens
• Every public page returns HTTP 200—no lingering 503s
• The Top-Selling Products block displays correctly on the site
• Error logs stay clean of new PHP notices or fatals for at least 24 hours after the fix

If you prefer to work on a staging copy, just let me know and I’ll set it up. SSH access can be enabled on request. Let’s get the site stable, secure, and selling again.
