Revolution Slider Gallery in Avada Theme Broken – Bug?

Hi there,

The Revolution Slider Gallery (built into Avada Theme) is broken on my site – I think it may be a bug. I have tried to fix it etc.

After fixing a justification error with the help of the Avada support team, the main bug still persists – that is, when you actually click on one of the images in a the gallery, the click and zoom feature is broken and comes out all buggy. It can’t be undone and the page has to be reloaded.

I couldn’t find anything to show me what has gone wrong with the Revolution Slider gallery in mosaic mode in the Avada Template. I have updated to the new WordPress, as well as the new Avada – The Avada support team couldn’t help, I am guessing it’s the Revolution Slider. The Envato Marketplace team are still getting back to me.

I’ve been trying to get this problem fixed for a few weeks now, so sorry if I come across sounding terse, but is there anyone with suggestions on how to fix it, or would anyone know of another gallery I can put into the Avada theme which will work?

Thank you again,
Aisha
