Common WordPress troubleshooting scenarios.

A business site went blank after a plugin update. wp-admin was also unavailable.

Common cause

The error log showed a fatal PHP error from a recently updated plugin running on an older PHP version.

Repair action

We backed up the site, disabled the failing plugin module, restored admin access, and documented a safer update path.

Result

The site came back online and future updates were moved behind a backup and staging check.

Paid traffic was reaching the checkout page, but orders stayed pending or failed.

Common cause

A cache rule was applied to checkout and callback URLs, so payment responses did not reliably reach WordPress.

Repair action

We excluded cart, checkout, account, and callback paths from cache, then retested payment status updates.

Result

Test orders completed and the store owner received a cache exclusion checklist.

Some visitors were redirected to spam pages, and search snippets started showing suspicious text.

Common cause

An outdated plugin left a backdoor and injected JavaScript into front-end templates.

Repair action

We removed the injected files, reset admin accounts, checked upload directories, and reviewed permissions.

Result

Redirects stopped and the site owner received hardening and monitoring recommendations.
