Hello Stefan,
I have just seen Ilana’s post and the slideshow has stopped working on my site too! Yesterday evening it just stopped working, has been working fine since it’s download on Monday (3rd March).
When trying to look into why it’s not working I have found I have nextgen gallery as a plugin also, although have not used it. A loading icon is produced with slideshow if nextgen is activated. If nextgen is deactivated there is just a blank space where the slideshow should be. For example on this page: https://rockup-climbing.co.uk/climbing/family-climbing-in-pembrokeshire/
I have had to put a back up slideshow on my homepage for the meantime – as need to have one that is working. But, would really like to use slideshow instead – so any help greatly appreciated.
Thanks,
Alec
