I installed the plugin discourse-math and activated it from the admin panel. But, MathJax does not render the imported posts (imported from OSQA) correctly.
However, if I edit the post (just clicking on ‘edit’ and not changing a thing) and save it, the math is rendered perfectly.
Can anyone help me in rectifying this behaviour ?

Give the exact URL of the plugin you used, please?

Sounds like you need to rebake all posts.
