TemplateModule has no attribute open_graph_metadata

I get this error when trying to render with the ipython theme. Various Mako based themes seem to work fine with the same source files.

I assume you just upgraded to Nikola v7. In which case, you should

rm -rf themes/ipython themes/boostrap3-jinja themes/base-jinja
nikola install_theme ipython

Faced the same error after installing the Srcco.de theme.

After installing the theme when I issue 'build' command, the same errors is shown.

How to fix this.

@Suleman-Elahi This looks like a bug in the theme. Please report bugs for themes in the nikola-themes repo instead of commenting on a mostly unrelated 8-year-old issue.

Oh sorry didn't know. I posted here because of the same error.
