Deactivate each one, one at a time until the error goes away. * if you can’t find which plugin is locking the mail function, send a mail to [info@itclever.com](https://wordpress.org/support/topic/postman-plugin-problem/info@itclever.com?output_format=md). it’s possible they have disabled mail on your WordPress system. * Plugin Author [Jason Hendriks](https://wordpress.org/support/users/jasonhendriks/) * (@jasonhendriks) * [11 years, 1 month ago](https://wordpress.org/support/topic/postman-plugin-problem/#post-5959658) * [@bangkok108](https://wordpress.org/support/users/bangkok108/) did you deactivate the plugins? also try temporarily deactivating the theme. another of my users had a [theme that was causing mail problems](https://wordpress.org/support/topic/contact-form-7-and-other-plugins-not-going-through-postman?replies=20). * Thread Starter [bangkok108](https://wordpress.org/support/users/bangkok108/) * (@bangkok108) * [11 years, 1 month ago](https://wordpress.org/support/topic/postman-plugin-problem/#post-5959665) * i did deactivate the plugins, but Contact form7 is still not working.always the same message pops up in red box.i contacted my hosting company who says everything works with other customers. * where can i find the Theme on WP? can you recommend me another contact form? thanks daniel * Thread Starter [bangkok108](https://wordpress.org/support/users/bangkok108/) * (@bangkok108) * [11 years, 1 month ago](https://wordpress.org/support/topic/postman-plugin-problem/#post-5959709) * hi from thailand this is the message that pops up in WordPress when i go to menus page: “If this message does not disappear, it means that UberMenu has not been able to load. This most commonly indicates that you have a javascript error on this page, which will need to be resolved in order to allow UberMenuto run. How to check for javascript errors” * it’s getting technical. do u know what’s wrong with javascript? * daniel gerbault [http://www.apsaraventure.com](http://www.apsaraventure.com) * Plugin Author [Jason Hendriks](https://wordpress.org/support/users/jasonhendriks/) * (@jasonhendriks) * [11 years, 1 month ago](https://wordpress.org/support/topic/postman-plugin-problem/#post-5959711) * No, I’ve never used UberMenu. * I use Safari as my web browser and to inspect Javascript errors I go to **Developer- > Show Error Console**. If you can do the same for whatever browser you use, I’m sure you’ll see the Javascript error. You can send the error to the developer of the plugin/theme as they are the best person to ask. * Plugin Author [Jason Hendriks](https://wordpress.org/support/users/jasonhendriks/) * (@jasonhendriks) * [11 years, 1 month ago](https://wordpress.org/support/topic/postman-plugin-problem/#post-5959742) * Daniel, thank-you for letting me login to your server. I discovered what was causing the conflict. There is a nasty (hidden) plugin of the “[Must Use](https://codex.wordpress.org/Must_Use_Plugins)” class installed in your WordPress by your [host](http://www.itclever.com/): * ```
