@Saurabh Vanve It seems like you are having trouble accessing your WordPress site through your custom domain after migrating it to Azure.
Firstly, it's important to note that when you add a custom domain to your Azure website, it can take up to 24 hours for the DNS changes to propagate. During this time, you may experience issues with accessing your site or certain functionalities.
Regarding your issue with deleting plugins, it's possible that the permissions for your custom domain are not set up correctly. To resolve this, you can try the following steps:
- Log in to your Azure portal and navigate to your WordPress site.
- Click on "Configuration" and scroll down to the "Domain names" section.
- Make sure that your custom domain is listed and set as the primary domain.
- Click on "Authentication / Authorization" and make sure that the "App Service Authentication" toggle is turned off.
- Save your changes and wait for the DNS changes to propagate.
After completing these steps, try accessing your WordPress site through your custom domain again and see if you are able to delete plugins. If the issue persists, you may need to check the file permissions for your WordPress installation and make sure that they are set up correctly.
(I also want to add that we state the best practice is to use a CNAME record when possible. In rare scenarios, the inbound IP address of your App Service could change, which would break your A record. For this reason, we always recommend CNAME records as they will avoid these scenarios.)
