Error in log

Go to global parameters
Tab "Automation"
Section "Automatic import of files"
Change "directory of automated integration files" to set it to value of existing folder
or Change "automatic import cron delay (in seconds)" to "-1" to disable the feature

Please post projeqtor log file

You have 3 errors logged :

1) import directory does not exist (OK, that object of acces to Global Parameters)
2) you imap definition is wrong (must also be changes on global parameters)
3) You ran CRON with DB stopped (on unreachable)

But I don't see any error that can explain non access to Global Parameters.
Try and doconnect / reconnect
