I have a client with PromoSlider on the home page and the auto advance is not working. Their theme loads its own jQuery (1.51) and I thought that's the issue as I see a JS error in Firebug @ line 171.. it attempts to call replace() method. The links work fine.
HOWEVER, they showed me a staging site which (they claim) is identical... same theme code and Promoslider version and WP core. And the PromoSlider advances properly.
Before I go nuts debugging... any ideas as to why the first does not work and the staging site -does- work? I'd like to just throw it back as a theme issue but since the 2nd site does work, I don't want to give in just yet.
