Hi,

Just wanted to let you know that this is still not solved. I was unable yet to conduct your recommended testing as I lack the skillset to comment out these javascripts.

understand.

but this remains a unique problem on your site.  and its hard to offer suggestions without more data.  I do understand the catch 22 with messing with a live site.

I am very disappointed with the support I am getting here. 

This has been opened for 14 days and the last item to fix before my site goes live and I do not see much support to resolve this.

well, frankly, a bit disappointed in  your unwillingness to try things…  this is a unique report that is only happening on your site…  we have already established that switching to a default wp theme and the problem goes away…  so something the wp theme is doing is conflicting with simple press…  but if you are unwilling to try some of the experimentations to isolate your local problem, how would you suggest proceeding?  we cannot conjure up a fix for your local issue if we dont know what it is when no one else is experience similar and we cannot duplicate…

I understand your concern with live site, but if that is the only place a problem is occurring, logic dictates its the best place to troubleshoot it too…

My developer found the culprit: it was YITH Ajax Search plugin. Disabled and it now works. 

You may close this ticket.

interesting… makes sense since something was messing with the json ajax response from jquery ui autocomplete…

but thought earlier you had said it didnt work with plugins disabled but did work with theme change… but maybe I am confusing issues..

none the less, great news!  with this solved and the vanishing forums solved, seems you are go to go for launch.  good luck!
