Does anyone have any ideas on this problem?
Anyone have any ideas if this exists?
Yes, for some reason, changing the width in the css file for the plugin would not work for me, I had to open the css file of the theme, and I found in a string in there for contact width; by changing this, it worked for the plugin.
Generally in your main theme css file, there is an option for width, you’ll need to adjust it in there. I had this same issue using the RT theme 11.
What payment system are you using?
