Hello Team,

Event management portal loaded a blank page after the deployment. When I checked the browser console, it showed below error.

Refused to apply style from 'https://org.powerappsportals.com/eventmanagementapp/styles.css' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled.

Refused to execute script from 'https://org.powerappsportals.com/eventmanagementapp/runtime.js' because its MIME type ('text/html') is not executable, and strict MIME type checking is enabled.

I have deployed the base portal version from the following

    There are situations where it is not possible to push the new website definition because of the changes to the underlying portal web pages. Portal web pages, web templates, and web files are used to host the event website when you host the website through Power Apps portal hosted. You need to update these entities manually if you make any changes to these entities. There is no automatic mechanism to update from version to version as it breaks the customer customizations.
