No addons in YAST can be open

They all give similar erros like this:

/usr/lib/YaST2/bin/y2base: symbol lookup error: /usr/lib64/YaST2/plugin/libpy2UI.so.2: undefined symbol: _Z16should_be_loggediRKSs

This is TW system on my portable drive, and is up to date.

I am not having a problem here. I am at 20160130. According to Yast, that plugin comes from the package "yast2-ycp-ui-bindings. I show the following versions as being installed:

yast2 3.1.163-1.2
yast2-ycp-ui-bindings 3.1.9-1.4

I am am recently encountering the same issue, have you found any work around it?

When you say your system is up to date, did you actually run the command to update your system?

Because this is TW (not any other openSUSE)

Yes I did, the actual problem was that somehow I’ve added the Leap repos in my Thumbelweed installation and this was causing all sort of miss behaviour. Removed that repo and all was good.
