On advice from @phenomlab I uninstalled the plugin, rebuilt, installed plugin again, rebuilt and it was ok.
This had also happened to himself before.
Is anybody having problems on self hosted site with Slick template? Widgets don't work and loading bar keeps repeating at the top of the page (when I say loading bar I mean the blue effect across the top when it loads). Other themes are working fine. Tried reinstalling rebuilding etc, nothing to be done.
Yeah it needs the widget areas I think those were added in 1.6.0, I will see if I can send a PR tonight. https://github.com/pichalite/nodebb-theme-slick/issues/10
Thanks guys, I really like that theme! It does have global sidebar and header, it was quite nice. Nothing working now though as regards widgets and it seems to be continuously loading or refreshing. I'm on Persona now but hope a fix comes.
