Actually I have experienced this error many times but not on a particular action.
last time i got this error when i was trying to log in.. after clicking ok please wait… message came but nothing was happening till 20mins so i have to refresh page & logged in.
how are you backing this database up, i seem to have zero success with both /tool user-manager database backup as well as using the webgui maintenance save
Sorry dude i dont mean to hijack your thread, just having a really hard time with this rc4 release and really need the help
/tool user manager database save name=mainsql.umb
/tool user manager database save-logs name=logsql.umb
Just tried a couple of minutes ago, at least it works for me
If you still are unsuccessful, please use the following procedure:
Try to make a backup
Check if you can see an error message by
/tool user-manage database print
If still unsuccessful, make a supout file right after the unsuccessful backup and send it to support at mikrotik dot com
Please note, that creating a backup can take some time, depending on your DB size. You can check, if the backup is over when User Manager web or console is responding again (it is unresponsive during a backup).
DO NOT use export, as it will not save the database properly! Console does not display all the attributes saved in DB.
Export can only be used as emergency, when nothing else works and you want to save at least some of the data. But it should not be used as regular backup approach.
