MoreGallery is outputting ‘pre’ tags into the [[+description]] placeholder.
Is there a way to prevent this and only output the value?
BTW, great Extra!
Hm, it’s supposed to only output the value. Any chance your pre tags are added in the chunk, or to the description itself when editing the image?
Aha turns out the rich text editor was adding it for some reason. Sorry, something I should’ve checked! 
Nothing to do with MoreGallery!
