Knowledge Base & Operational DocumentationWhy Does a Hosted Website Return an Error After a Hosting Plan Change?
Changing a hosting plan can alter resource limits, PHP handlers, database settings, IP addresses, or service configuration. The site may fail only after the new plan becomes active.
What to check
Compare old and new plan settings, assigned resources, runtime version, account mapping, DNS and IP, database permissions, and recent error logs. Check whether scheduled jobs or add-ons exceed the new limits.
Recommended next step
Resolve incompatibilities with the hosting provider and validate the application under the new configuration. Confirm backups, mail routing, and monitoring after the plan change.
