Dear,
When I use the email contact form is not sent, get the following error:
‘ Failed to send your message. Please try later or contact the administrator by another method. ‘
Hello,
This problem occurred 10 days ago. (Approximately)
Everything was working normally until before that.
We have tested connection and others, the server is working correctly.
Do you use “WP Super-Cache” plugin?
This issue can be related with this plugin.
Also if you can send us your wordpress account, we would like to inspect this issue in a more details.
Thank you.
