Hello Lee-Ann,
I am sorry for the delay of this reply.
Regarding on the container category link clickable issue, I've applied the fix inside your /components/com_easydiscuss/themes/simplistic/categories.php and it should be working fine now.
>> 1) Facebook autoposting is not working.My app is setup and login with FB works but I cannot seem to get autoposting to work...
Answer : Would you mind if you can provide us with your Facebook access details so we can help set up the facebook autoposting for you correctly?
>> 2) After posting a new discussion the redirect shows a 404 and I have to refresh it but the post does save (needs to redirect to the post (default)
Answer : It seems like the misconfigured facebook apps causing the redirection issue when autoposting is enabled. I've temporarily disabled the autoposting and the redirection is working properly now.
>> 3) Facebook share only shows sometimes on topic detailed page. It works when it wants??
Answer : I am sorry but I'm not quite understand you here. Do you mean that when the discussion post is shared on facebook the content is not showing properly? I tried to share one of your post in facebook and it seems lie the content did get generated properly. Check my screenshot here,

>> 4) My template mobile view does not show 100% correctly (i.e. mobile menu not showing instead it is Desktop menu) but only on the single category page. the rest of the pages work fine. *This is only on mobile devices and not browsers).
Answer : May I know do you make some customization with your easydiscuss toolbar? By default it should showing icons instead of text. Perhaps you can revert it back to original so that it will display properly in mobile view?
>> 5) After performing a search - the url shows: search.html?query=ietopic&option=com_easydiscuss&view=search&Itemid=264 .. Is there a way to rewrite this to hide easydiscuss from search?
Answer : Unfortunately that's the current behavior of easydiscuss search and I believe it does not affect the SEO of your site as it only appear during search result.
