Thread:Extension talk:Header Tabs/parameters have no effect

I am using MW 1.22.1 and the current master branch of HeaderTabs. I have set $htDisableDefaultToc = true; $htGenerateTabTocs = true;

but they seem to have no effect. The MW TOC is still displayed and no TOC is generated on top of each tab. See this example. Maybe some more extensions incompatibilities? Or doesn't it support MW 1.22.x? Or is the order of loading this extension important?

Anther point: When changing  or   I need to restart Apache to take effect. That's strange.
