pagetree not shown
After update from 6.2.12 to 6.2.13 the pagetree is not shown anymore.
The filter for the tree is still working, so I get some pages shown when I enter i.e. 0 or 1.
Removing the filter shows a blank tree-window again.
I never see any PHP errors or database errors even I activated all basic debug-options in the install-tool.
