Authorization Issue, page will only display when logged into site.

[paulmcdonald74]

Steps to reproduce the issue

This is an error with a basic custom component that worked prior to 3.8. It is a basic page that pulls info from a custom table. When not logged into the site, the page will not display and displays "Error You are not authorised to view this resource."

Expected result

It should display to public on website (not logged in) and was doing so up to 3.8.

Actual result

Error
You are not authorised to view this resource.

Additional comments

What is something to look for in order to fix this? Appreciate any assistance. Fyi, this custom component uses JViewLegacy

Check the menu item permission and check the component access right. I don't see why it would stop working.
