Hello,
I recently updated WordPress core, themes and all the plugins, and then started having problems with WP Mail SMTP failing to work properly with Contact Form 7. I tested by disabling plugins, and trying the Twenty Seventeen theme, and it is definitely caused by these two plugins not working together. However, I’m not sure why, as nothing shows up in the logs or in the console.
WordPress 5.2.1
Contact Form 7 5.1.3
WP Mail SMTP 1.4.2
The test feature of WP Mail SMTP sends correctly.
Contact Form 7 sends correctly if I disable WP Mail SMTP.
If I have WP Mail SMTP running, I get the red border and a “failed to send” message in CF7.
I tried disabling the html-email feature of CF7, as I saw that in previous versions this was causing an error. It didn’t help.
Thank you for any advice you can offer.
Charlie
