Graphic Display PG2 shows grey only
I have a Problem on the Aspect Server of a System 800xA 5.0 SP2 Rev E.
All Graphic Elements and Graphic Displays PG2 are not working, only a grey background is shown like the Element would not exist. The Graphics Builder can not be opened - the Edit option in menu exists but nothing happens when i choose it. Other Aspects work correctly.
The same PG2 Graphic Aspects work correctly on all other Nodes in the System and can be edited.
This has worked some time ago and "nothing" was changed, at least not that i would know.
Anyone has an idea where the issue could be?
