Hi Maverick,
I have the following issues on my website http://www.engg.tv/.
1. The page does not refresh after posting an answer. The problem started recently after enabling and disabling the reCaptcha. The symptoms look similar to this issue http://www.corejoomla.com/forum/community-answers/4966-does-not-refreshes-page.html

2. The Ajax search stopped working after upgrading to CA 1.5.4

3. The delete answer also does not refresh the page.

4. Delete question is stoned. Does not respond at all.

5. I have added the patch for the content plugins to work in the CA. The content plugins work in the normal Q&A section but not in the following sections
1. My Answers
2. Jomsocial activity stream.

I will send the site details through the contact form

Thanks
