VM Vendor 1.3 Issues

Ok I assume you mean in the template manager. I have set optimize css to "no"

Good, now we can work
open

yoursite/components/com_vmvendor/assets/css/bootstrap.min.css
and remove or comment out line49:

webkit-box-sizing: border-box;
box-sizing: border-box;

you can remove it from the bootstrap.css but then have to minify again the css file with something like
cssminifier.com/

and rename the file: bootstrap.min.css
This should fix your background conflict. I could verify this using Chrome 's inspect feature.
Let me know

Where is this code? I didn't find it in the cb plugins xml or php files.

I have also commented out the line 49:

/*,*:before,*:after{-webkit-box-sizing:border-box;-moz-box-sizing:border-box;box-sizing:border-box;}*/


It did not fix the issues...

This message is in regards to fixing the images not displaying in the cb tab... I could not not find the code that you mentioned before.

I did not find this line of code in the plugins xml or php files. Where is this code located?
