We have strange issue. On our site, there is no cache plugin. Turn nonce is off. For some users it works fine but for others not. It says about validation code expired. No matter in what browser it is opened in the same device. On one device it works, on other not.
We have tried demo forms here on your web and it works fine in all devices. I am not sure what the cause is.
Could you please advise?
Hi Tony can you please remove Google Captcha setting from EA and try again.
Thank you, I removed Captcha as a first idea. 2 days ago, I have new version of the plugin 3.4.0 from today. Refreshed cache on computer with problems, but nothing is changed. Problem remains :/
Just solved, the problem – wp-admin folder was blocked for non admins IPs with .htaccess file,and plugin is not compatible with this security improvement 🙂
