How exactly are you doing this??
Just trying to upload under upload settings tab. I think i may need to upgrade. I am trying to add a lightroom slideshow to my muse website on business catalyst.
Ok, now there is some clarity... thank you.
However you are trying to load a slide show exported in what format from which version of Lightroom to which version of Muse??
However I would suggest you also post in the Muse forum as it is likely the answer is there...
