I resolved thanks to this post: Contact Form Message Pattern
I’ve inserted this example of code in Divi Contact form option:
My name is %%Name%%, my message is %%Message%% and email address is %%Email%%.
Thanks a lot for your support and your plugin!!! ??
Hi, thanks a lot for you answer and support!
Pherhaps, could be the child theme?
Whatever this isn’t a real problem, the plugin seems is working, so thanks again for your precious time.
thanks a lot for your great support!
Your solution had resolved my problem (I left the value of 30)!
Only a problem remain: the toolbars icons become like “ball” icon of your plugin, instead of default icons… Could I try to change the value to 50 or 10 to resolve or it’s a completely different problem?
