Unfortunately we could not examine this problem yet on your site, because the problem “disappeared”.
First I wanted to see the original content of the page without the plugin, that is why I deactivated. Then I activate again, and I could not see the problem.
I do not know the reason, because we have not got possibility to debug it yet. Probably there is any conflict with something on your site.
We have not realized this kind of problem yet, and have not got any support ticket about similar problem. That is why I suppose this is a kind of local problem on this site.
Please let us know if the problem occurs again.
