Updating Routing Rules

• Framework-Specific Fixes: Different web frameworks handle routing differently. For example, in WordPress, you might need to adjust your permalinks, while in Django, you would modify the urls.py file. Understanding your framework’s routing rules is crucial to fixing the 405 error.
