Hello,
Please see error attached.
I have configured Customer Service IMAP settings and after saving it took long time and ended with 500 error, now everytime i try to get in i have long wait and error, debug shows this message
UPDATE: it was mybad but could be fixed / manged somehow on Presta side.
I entered wrong IMAP pass and had to change it in ps_configuration table, where it is stored as plain text, not sure if its safe enough
Nevertheless now its working
