Hello Yuval,
Thank you so much for your help. However, I can’t work this plugin. I am not good coder and when I close my exiting add-ons, my web site look like very bad. ?? So, I got enable again my add-ons. By the way, when I close all add-ons the plugin doesn’t work still.
I can’t try default theme suggest, because as I said I am not good coder. Thank you again for you help and your plugin.
I am not sure write in here this message but I write. I found another plugin and the plugin is working. If anybody read of this message who like not good about coding, they can try to Wpforms.
Best wishes
