Hi Paul, thanks for replying. I am hoping to make this less confusing in Tip 3 you shared with me, I removed the reference to CC: part all together. Saved. Cleared my browser cookies and cache.
Then on the server I checked in everything, cleared the server cache, cookies, browsing date and images. Closed my browser. Re-opened and tried to send a message to see if it would show the prohibited input U 00000020 message of sending test email.
The issue still exist after doing all of this. I take it that putting {{e-mail}} is what was causing the problem.
I'm ready for the next place to look with your guidence. Thank you. I hope we can fix this together and that I can understand and learn and grow from this? See screenshot of my settings in Hidden Content.
