Blog 503 Error Issue and Solution
503 Error Occurrence on Main Domain
After the automatic update to WordPress 6.3, a 503 error occurred on the main domain.
Despite various attempts, such as disabling plugins, the issue remained unresolved.
Resolution by Stopping X Accelerator and Changing PHP Version
The problem with the main domain was resolved by stopping the X Accelerator, but this led to a 500 error on the subdomain. Ultimately, changing the PHP version to 8.1.12 resolved all issues.
Considerations
Identifying the exact cause was challenging. The issue could have been due to multiple factors, including server settings, plugins, WordPress version, and PHP version. A multi-faceted approach is crucial for effective website management.
