Thanks very much for the reply and the CSS you have sent.
While this functions as a workaround, it does not solve the problem. For example, if I place a caption under the Featured Image or if I italicise the first paragraph then the CSS fails to work.
Surely the problem is within the dropcap shortcode, it used to work fine without this problem. This problem has only started during the last couple of updates. I have an old copy of Pro installed on localhost here and it works fine!
Furthermore, I am not asking for custom code which I understand is not covered by the scope of your support, I am merely asking for the dropcap shortcode from your theme to work the way it is meant to.
Thanks
