Hi Andreas
Actually fixed by removing the image and just using a standard link, works fine now, maybe just an issue with themes that use some kind image plugin.
The plugin is being used internally so don’t have a public link I’m afraid.
The theme used is Shutter from The Happy Bit. It actually supplies an shortcode for not activating the prettyPhoto plugin, but that wasn’t a viable fix.
Thanks for the attention ??
