I restored my system back to 1.9.3 (restore DB and copied back 1.9.3 files from setup)email fetching start working again.I will clone it tomorrow for upgrade testing.If developers need something from my system prior to upgrade, I will be glad to provide the data. (and post upgrade to isolate the issue).BTW, I am running separate osticket system in my environment - started with version 1.9.3 - that one upgraded OK, with email fetching working.But my main system, I believed I started with 1.8 and upgrade to every version when it become available . That the one that had issues.If I install brand new osticket 1.9.3, beside DB restore, what else I need to copy over to keep all the settings and tickets attachments? (if it is possible)
