Blank screen when approving regisrtations and Posting to a GroupJive wall.

I don't know if this is a Community builder issue, a template issue or specific to group Jive. What is common to all three is the issue.

• If an individual registers to join my website www.techknow.org.uk Admin/Mods can see this. If they approve the individual, the page goes blank. The Admin/Mod has to do a page refresh. The user is approved, however, this issue has only arisen since we installed a few months ago the CB Coolness template.
• If a member is in our Group Jive and wants to post to the wall then a similar thing occurs. On posting to the wall, the page goes blank and a page refresh is required.

Info:
We are running
CB Latest 1.9
CB Group Jive Latest 2.7

Here is the error log below: Can anybody advise on what steps I need to take here to correct this problems?

All of those are warnings except your UddeIM issue, which is a fatal error. To fix the warnings please see my reply to the below topic.

As for UddeIM it looks like you have UddeIM CB plugin installed in CB > Plugin Management while also having our built in Private Message System plugin enabled. Disable either the UddeIM plugin or Private Message System plugin within CB > Plugin Management so you're only using one. If you issue persists please post to the UddeIM forums below as the error is coming from UddeIM directly as the developer of UddeIM may know better what to suggest.
