Contact form does not work
If your contact form does not work:
1. First of all, Please make sure correct email address is pointed in Dashboard -> Settings -> General -> Email Address (fig.1.1) and Dashboard -> Theme Options -> Contact forms -> Email (fig.1.2):
2. It would be wise to check whether the theme is installed to the correct folder: /wp-content/themes/dt-the7/.
3. Secondly, you should try to deactivate all plugins.
4. In some cases, the following plugin installation may solve the problem: Easy WP SMTP. Start from selecting the Default mailer (fig. 2) and sending the test email under Easy WP SMTP -> Send a test. If it doesn’t help, try choosing other available free mailers.
