Status:	Answered	TWiki version:	4.2.3	Perl version:	5.10.0-37.6
Category:	ControlsPlugin	Server OS:	SuSE Linux 11.0	Last update:	16 years ago

I just installed ControlsPlugin using installer. I get this error when I attempt to view the ControlsPlugin topic. I am clueless as to how to resolve the problem! The last entry in warn20090903.txt copied below:

Discussion and Answer

This plugin calls an unpublished internal TWiki function. It now apparently breaks on a later TWiki release. The plugin author or someone with Perl skills need to fix the plugin.

Thanks, Peter. I was afraid of that. The ControlsPlugin is documented as tested within TWiki 4.0.0. I guess it got broken somewhere along the way to 4.2.3. I'll see if I can nudge the author to look at it, since it really looks like it could be useful to me.
