Errors on Page with Polls

Hi.
Liking the product, just installed it to see how it integrates with JomSocial.
However, when users try to vote, or view the votes, the following errors are shown...

How do I solve this, as it has an impact on whether I go forward and use this component long term on the site. The most prominent problem is when people register a vote, they get the timer graphic, and it doesn't progress to the votes screen.

Thanks
