Error with AliasPlugin (Can't call method "takeOutBlocks")

When I turn on the AliasPlugin, I can't edit or save a new topic. Here is the error-message:

Can anyone tell me, what is going wrong?

Are there any other plugins that you enabled on top?

Which Foswiki version are you using?

Which AliasPlugin version are you using?

I've tryed to turn off all the other Plugins, I'ved installed, but the effect was the same.

So, now I've connected foswiki with internet und at the configpage/extension shows, that Aliasplugin needs an update. And now it don't make errors.

I'm mortified. Less than a few week have passed since I've download the plugin and so I've used this for a new installation. anyway, I've learned from my mistake and hope, you can forgive my inexperience.
