@Michael_Pryor thanks for responding.
I just followed what you said and unfortunately it didn’t change anything. My problem is that basically ever since I did the fix above (changing Load Mechanism), GH doesn’t seem to acknowledge that Dendro even exists. Even when I delete and reinstall it (unlocked). To be clear, Dendro used to show up inside GH, but it doesn’t now.
It no longer shows up in the “Plug-in Loading” section that Charles referenced (see image). Dendro used to show up in the area circled in red before I changed the Load Mechanism.
Thanks for your help!
