I had the CBAuthorbot properly working over J1.5.11, but after updating my site to J1.5.12, the full <a> meta-tag started to get displayed as text instead of the interpreted result.
I solved this removing the "escape" phase in the J core's templates (joomla_root/components/com_content/views/frontpage/tmpl/default_item.php & others for blog category, blog section and article itself).
Does anybody knows a better way to get back this functionality?
