I had some BIG problem with Yet Another Related Posts Plugin 4.2... galleries ans single pics not working at all with YARPP On. It just showed Nextgen shortcodes.
That solved, (and all plugins off, and checked with another themes, and another browser), and having some problem with single pics:
-Where it should be a single pic, now the web shows "no images were found".
Here you can check some samples (gallery working, single pics missing):
Shortcode used is [singlepic id=2667 w=350 float=center], is that the problem?
Any idea? Thanks!!!
