Warning: A non-numeric value encountered in – message

@scordova3 Hello, Thank you for writing. I do not see this error in my tests: https://www.boltonstudios.com/before-after-images-for-divi-demo/

Does the error disappear when you deactivate Before + After Images? Can you try uploading your images to the Media Library first, then opening a Before/After module and adding your images to it from the Media Library, and does that solve the problem?

Hello Aaron, yes the error disappear when I eliminate the modulo in divi builder. I try the solve that you told me, but I have the same error.

I ran into this same issue. I was able to resolve it by changing the PHP code to this:

$matched = ( @abs( $constrained_size[0] – $expected_size[0] ) <= 1 && @abs( $constrained_size[1] – $expected_size[1] ) <= 1 );

Add @ in front of the abs value.
