I am using the smush it pro plugin on my site, using

Hi
I am using the smush it pro plugin on my site, using the AVADA theme. It is not really processing any of the images when i bulk smush and cant figure out if it is something to do with the theme or not? When i upload an image file, the upload fails and usually i have to do it a couple times before it appears.
I have used the plugin on other themes and it has been fine.

Hopefully you can help
