I recently installed icingaweb, everything working as expected, except whenever i click on services, under overview or problems i am getting this - Deprecated : bin2hex(): Passing null to parameter #1 ($string) of type string is deprecated in**/usr/share/icingaweb2/modules/icingadb/library/Icingadb/Redis/VolatileStateResults.php** on line135
did you run all migrations after upgrading icingadb or is it a fresh installation?
what the version of your icingadb daemon?
does the redis server work correctly?
