WordPress Website Stopped Working? 5 Common Causes and What to Do

When a WordPress website stops working, the worst reaction is random clicking. Start with a calm diagnosis and a backup.

Plugin or theme conflict

A recent update can conflict with another plugin or the active theme. This is one of the most common reasons for a broken site.

PHP version or fatal error

Old PHP versions and incompatible code can cause white screens, critical errors or broken admin access.

Hosting resource limits

Cheap hosting can run out of memory, CPU or process limits, especially during traffic spikes or backups.

Malware or hacked files

If the website redirects visitors, shows warnings or creates unknown users, treat it as a security incident.

Database or file damage

Corrupted files or database tables can break pages, login or media. A tested backup is often the fastest recovery path.
