I got these errors opening the latest devel LeoPyRef.leo -
initWriteIvars Did not create ../plugins for ../plugins/leo_cloud.py
===== PERFECT IMPORT FAILED ===== leo_cloud.py
len(s1): 585 len(s2): 0
all common lines match
initWriteIvars Did not create ../plugins for ../plugins/leo_cloud_server.py
===== PERFECT IMPORT FAILED ===== leo_cloud_server.py
len(s1): 35 len(s2): 0
all common lines match
There was also an error dialog that those two files would cause errors on closing the outline, so they could not be saved.
