Same problem.
I've got a feeling it is all about new update. Before that all was OK.
First I found,
1) before crash I have changed dir from /manager to /ispmanager, bet after adding new domain, ISPM does not start by WEB and conf file consists previous setting with /manager
2) in log file, when loading /manager (like loop), goes:
Code:
