5.1 Problem with http://userman

RouterOS General
1

RB493ah / Firmware 2.29

The first login was ok, I picked up an user, and view the sessions, all ok. Than I hit Logs in the left pane and after that an error comes up and I am no longer able to get into /userman also to the /WebFig - stands only on Loading. With 5.0 I had no problems.

The following client application error has occurred:

Cannot process ServerMessage (Phase 1)

Error Name: TypeError
Error Message: librariesElement is null

Please contact your server administrator.

I reboot the Router - logged into userman again, hit Logs and the same problem, after that Userman/WebFig are no longer working until the next reboot.
