Same for the newest release (7.3.6) we upgraded to afterwards. * Any idea? * Best regards * Thread Starter [wco63](https://wordpress.org/support/users/wco63/) * (@wco63) * [5 years, 6 months ago](https://wordpress.org/support/topic/e_error-wordpress-mail/#post-13764004) * Hi Adam, any idea? * Thread Starter [wco63](https://wordpress.org/support/users/wco63/) * (@wco63) * [5 years, 6 months ago](https://wordpress.org/support/topic/e_error-wordpress-mail/#post-13771274) * Hi Adam, * we still cannot use your product please reply! * TIA Best regards * Plugin Support [Patrick – WPMU DEV Support](https://wordpress.org/support/users/wpmudevsupport12/) * (@wpmudevsupport12) * [5 years, 6 months ago](https://wordpress.org/support/topic/e_error-wordpress-mail/#post-13773074) * Hi [@wco63](https://wordpress.org/support/users/wco63/) * Sorry for the delay on the reply, * The ticket replies can take 24 hours, but shouldn’t be longer than that. * It is possible other plugin or theme is conflicting to Hustle, * Do you have a staging website to run a plugin conflict test? * You can use a plugin for example: [https://wordpress.org/plugins/wp-staging/](https://wordpress.org/plugins/wp-staging/) * Make sure to have a full backup, and follow this flow: [https://premium.wpmudev.org/wp-content/uploads/2015/09/Support-Process-Support-Process.gif](https://premium.wpmudev.org/wp-content/uploads/2015/09/Support-Process-Support-Process.gif) * Let us know the result you got.

What is interesting I think is that all of the buttons in Hustle are only black boxes, is that a hint? * If you want to have on the settings I can create a user for this page for you? Where can I send the credentials to?

We only wanted to show the popup on some pages and defined that under Visibility. After removing that setting the popup worked again. * Maybe you can check that with your dev guys because we would prefer to show the popups only on special pages in the future… * Thanks for the support, you can close the ticket. * Best regards and happy Christmas Werner * Plugin Support [Patrick – WPMU DEV Support](https://wordpress.org/support/users/wpmudevsupport12/) * (@wpmudevsupport12) * [5 years, 5 months ago](https://wordpress.org/support/topic/e_error-wordpress-mail/#post-13830685) * Hi [@wco63](https://wordpress.org/support/users/wco63/) * Thank you for the update. * I’m happy to hear you found the issue. * Have a wonderful Christmas too * Best Regards Patrick Freitas Viewing 11 replies - 1 through 11 (of 11 total) The topic ‘E_ERROR (WordPress mail)’ is closed to new replies. * ![](https://ps.w.org/wordpress-popup/assets/icon-256x256.gif?rev=3446944) * [Hustle - Email Marketing, Lead Generation, Optins, Popups](https://wordpress.org/plugins/wordpress-popup/) * [Frequently Asked Questions](https://wordpress.org/plugins/wordpress-popup/#faq) * [Support Threads](https://wordpress.org/support/plugin/wordpress-popup/) * [Active Topics](https://wordpress.org/support/plugin/wordpress-popup/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/wordpress-popup/unresolved/) * [Reviews](https://wordpress.org/support/plugin/wordpress-popup/reviews/) * 11 replies * 3 participants * Last reply from: [Patrick – WPMU DEV Support](https://wordpress.org/support/users/wpmudevsupport12/) * Last activity: [5 years, 5 months ago](https://wordpress.org/support/topic/e_error-wordpress-mail/#post-13830685) * Status: resolved
