anthill.exampletheme on Plone 4.2 - plone

Question

I'm trying to install a Plone skin called anthill.exampletheme 0.2 on Plone version 4.2 but it keeps returning the error below. The extension, anthill.skinner 0.8 installed and runs fine by itself but not the example theme. Please help!

Answer 1

According to:
https://dev.plone.org/ticket/10676
anthill.exampletheme's main_template is not Plone 4 compatible. Replace its main_template with a Plone 4 main_template (e.g. from sunburst) and you may get further.
