SuiteCRM8 embedded as an iFrame not working

I have it working, but depending on what release of 8 you are working on, you need to do some manual modifications to some files and you also need to download a newer SugarApplication.php that was fixed.

Details of the manual mods I did as well as the Dev fixed file are available through the posts below. the xsrf-token-lax issue has not been addressed yet by Dev, so if you manually update it, be aware for upgrades.
Hope that helps you.
