I had a problem with sending emails with your plugin and just want to share what I found.
First of all, I use your plugin in various websites since the beginning – almost 10 years. Thank you for your great work!
And that’s why I want to help you to eliminate a strange issue. Usually, I set up custom subject for the emails. For the first time I put a date in the format: dd.mm.yyyy and this caused the error:
There was an error trying to send your message. Please try again later.
Аnd the strangest thing is that this is the subject of only one form but it breaks the whole functionality of sending emails for every form in the website. If I remove the dots from the subject everything works like usual.
Probably is some kind of missed sanitization, I don’t know. But would be good to check it. Meanwhile, I won’t use dots in the subject field. 🙂
The website works with the latest version of the plugin and WP.
