Post types tab problem

Hello,

I installed the plugin.
When I enable the Post Types Restriction in “Pages visibility”, the “Widget Options” settings page does not show the available widgets. So, I have to disable the “Post Types Restricton” if I want to access the widgets.

Can someone tell me how to reset the parameters in the Mysql database so that it should work.
Is there a conflict between this plugin and another one ?

Thanks for help!
