Provider created custom CCP (Customer Control Panel) menu item which has to open a page on some external webiste.
When customer clicks on the custom menu item in CCP a blank, corrupted page or other unexpected content is shown.
POA allows configuring custom items for Customer Control Panel, as described in POA Provider's Guide.
These custom menu items may be configured to open a screen from an external website. If the external website does not open correctly, custom menu item in POA will not work as well.
Locate the custom item that does not work in POA Provider Control Panel at System Director > Configuration Manager > Custom Menu Manager > CCP Menu Structure.
In the 'URL' field, find the URL that opens when this menu item is clicked.
Verify that the URL opens correctly. Modify the URL if needed.
