I have just upgraded MONyog from 4.72 to 5.12 and I am having some isssues with server settings. I have noticed that several servers that in the past were labeled as replication slaves have lost that designation [this may have happened in a previous upgrade and went unnoticed]. When I try to correct this setting the page 'dies' upon submit.
Some of these severs have been set up for years in MONyog and I am not looking forward to rebuilding all of the settings.
Would anyone have any suggestions on where to start troubleshooting this issue?
