[opencms-dev] Workplace user thrown out while editing after a very short time. Any ideas?

[Manfred Schenk]

Hello list,

A user of my opencms-installation (Version 7.5.0) is logged off the
workplace while editing after a very short time.
He has the projectmanager role for the project he works on.
Does anybody of you have some idea where to look at?

Regards,
Manfred


This is the error shown to the site manager before he is logged off:
