Hello,
I've installed, enabled and activated "Maintenance Mode for Jira" plugin few days ago. Next, disabled the plugin using "Save and Disable - Button".
Today I've found, that my email puller stoped working, and jira reports it is "Disabled by system flag"
Mail fetching was disabled with the -Datlassian.mail.fetchdisabled=true or -Datlassian.mail.popdisabled=true JVM argument before JIRA was started. JIRA cannot fetch email until you remove the JVM argument and restart JIRA.
I've inspected my setenv.sh file, and found "DISABLE_NOTIFICATIONS" line is commented out. Despite that I can still find "jira.mail.fetch.disabled : true" in jira startup log.
Also tried disabling, removing, reinstalling etc. plugin from plugin manager - no luck here.
The only change I've made is installing and using plugin, as mentioned above.
Hoping for quick help from You.
