I have two MacBook Pros. They are both running the same OS level 10.13.5 High Sierra 2158.LogosLogs.markflannery.20180610-113840.zipand on the same network. One is working fine, the other is giving me the Red Exclamation Mark inside the sync circle. I have run the log capture file and have attached it to this post.
It is likely that your Guided Learning database is corrupt.
Delete the folder /Users/markflannery/Library/Application Support/Logos4/Documents/8k10xmbk.p56/GuidedLearning and restart Logos.
Dave,
Thank you, that fixed the problem.
Blessings,
Mark
