When connecting with usermin the user cannot read his mailbox (INbox)
Error: 500 - Perl execution failed – sdbm store returned -1, errno 22, key " line 795. — /extensions/mail/messages.cgi?id=INBOX&folder=&start=
We tried to fix according to
https://archive.virtualmin.com/node/23642
and
https://archive.virtualmin.com/node/16737
We checked the quotas (all unlimited) and deleted (renamed) the index files.
No result.
Mail through IMAP and POP work normally, only the INbox webmail fails.
Any suggestion? Thank you 
After update to Webmin 2.021-1 and Usermin 1.861-1 = Same result (picture)
