If I'm using a shared hosting environment, how can I troubleshoot 500 errors related to .htaccess, given that I have limited control over server configurations?

In shared hosting, contact your hosting provider's support. They can often provide assistance with server-level configurations and error logs. Carefully review your .htaccess file, paying attention to directives that might be incompatible with the shared hosting environment. If possible, avoid advanced .htaccess configurations that can conflict with the server's global settings. Always back up your files prior to any changes.
