I am having a little trouble with upgrading my site from 4.3.15 to 5.1.6. Everything went well without error. But I noticed the register/login links don't have the modal classes (no more pop-up window). Apparently, the actions.xml profile is not applied during the upgrade and the "join" and "login" actions are not updated with modal property.
I can certainly just manually add the property in the backend. But I wonder if it is supposed to be manually done or I did something wrong and missed a few upgrade steps. Thank you for any insight.
