I'm trying to add a slideshow to a page, it starts uploading the images but stops at 90% and stay there for 10-30 minutes.

Have already tried to cancel, close the tab... When I close the navigator and open the site editor again, the slideshow is not there and I can try again... Then in the 90% it freezes again!

Have tried with Chrome and Safari.

Any help?

Best regards,

Rodolfo
