[Zope] import error

hi all, The importing of my site is getting failed due to an error: "Input MIME type 'text/x-web-markdown' for transform markdown_to_html is not registered in the MIME types registry" I can't re-export my site as my system got crashed and i have only my backup which is a .zexp file. Is there any other possibility? Please help. Thanks in advance. --------------------------------- Bollywood news, movie reviews, film trailers and more! Click here.
