Title: Form Submission Error Last modified: June 2, 2021 --- # Form Submission Error * Resolved [elieelia9](https://wordpress.org/support/users/elieelia9/) * (@elieelia9) * [5 years, 1 month ago](https://wordpress.org/support/topic/form-submission-error-8/) * Hi there, * I seem to be getting an error when submitting any form on my website. When trying to access settings on the forminator plugin, I get the following error: * `Fatal error: Uncaught Error: Undefined class constant 'DOMAIN' in /home/marcosin/ public_html/wp-content/mu-plugins/wpmudev-forminator-hidden-input-time-field. php:79 Stack trace: #0 /home/marcosin/public_html/wp-includes/class-wp-hook.php( 292): WPMUDEV_Forminator_Hidden_Input_Time_Field->wpmudev_forminator_vars_lists( Array) #1 /home/marcosin/public_html/wp-includes/plugin.php(212): WP_Hook->apply_filters( Array, Array) #2 /home/marcosin/public_html/wp-content/plugins/forminator/library/ helpers/helper-fields.php(365): apply_filters('forminator_vars...', Array) #3/ home/marcosin/public_html/wp-content/plugins/forminator/admin/classes/class-admin- data.php(126): forminator_get_vars() #4 /home/marcosin/public_html/wp-content/ plugins/forminator/admin/classes/class-admin-data.php(36): Forminator_Admin_Data- >admin_js_defaults() #5 /home/marcosin/public_html/wp-content/plugins/forminator/ admin/classes/class-admin.php(96): Forminator_Admin_Data->get_options_data() # 6 /home/marcosin/public_html/wp-includes/class-wp-hook.php(292): Form in /home/ marcosin/public_html/wp-content/mu-plugins/wpmudev-forminator-hidden-input-time- field.php on line 79` Viewing 8 replies - 1 through 8 (of 8 total) * Plugin Support [Nithin – WPMU DEV Support](https://wordpress.org/support/users/wpmudevsupport11/) * (@wpmudevsupport11) * [5 years, 1 month ago](https://wordpress.org/support/topic/form-submission-error-8/#post-14516207) * Hi [@elieelia9](https://wordpress.org/support/users/elieelia9/), * Are you using the latest version of the Forminator? We have noticed such issues would occur if the plugin isn’t updated to the latest version or if there was an issue with updating the plugin. * If you are already using the latest version ie 1.14.11 then please re-install the Forminator plugin and then check whether you get the same issue or not? * Please do let us know how that goes. Looking forward to your response. * Kind Regards, Nithin * Plugin Support [Patrick – WPMU DEV Support](https://wordpress.org/support/users/wpmudevsupport12/) * (@wpmudevsupport12) * [5 years, 1 month ago](https://wordpress.org/support/topic/form-submission-error-8/#post-14516965) * Hi [@elieelia9](https://wordpress.org/support/users/elieelia9/) * Allow me to jump here too. * It looks you are using this mu-plugin: [https://gist.github.com/wpmudev-sls/a3c3d3268a7168b3599fccc1b48d341d](https://gist.github.com/wpmudev-sls/a3c3d3268a7168b3599fccc1b48d341d) * Can you please replace it where it says Forminator::DOMAIN replace it using “ forminator”, for example: * `'user_ip' => esc_html__( 'User IP Address', 'forminator' ),` * Best Regards Patrick Freitas * Thread Starter [elieelia9](https://wordpress.org/support/users/elieelia9/) * (@elieelia9) * [5 years, 1 month ago](https://wordpress.org/support/topic/form-submission-error-8/#post-14546154) * [@wpmudevsupport12](https://wordpress.org/support/users/wpmudevsupport12/) I’ve made the replacements, but the error persists. * [@wpmudevsupport11](https://wordpress.org/support/users/wpmudevsupport11/) My forminator plugin is updated to the latest version. Will uninstalling it and re-installing it cause me to loose any forms I’ve created or any submission retention? * Plugin Support [Nebu John – WPMU DEV Support](https://wordpress.org/support/users/wpmudevsupport14/) * (@wpmudevsupport14) * [5 years, 1 month ago](https://wordpress.org/support/topic/form-submission-error-8/#post-14548005) * Hi [@elieelia9](https://wordpress.org/support/users/elieelia9/), * You can choose to preserve the data and setting when the plugin is removed. Please find the option at **WP Dashboard >> Settings >> Data**. However, make sure to take a full backup of the site as an easy restore point if something goes wrong. * Reff: [https://wpmudev.com/docs/wpmu-dev-plugins/forminator/#data](https://wpmudev.com/docs/wpmu-dev-plugins/forminator/#data) * Kind Regards, Nebu John * Thread Starter [elieelia9](https://wordpress.org/support/users/elieelia9/) * (@elieelia9) * [5 years, 1 month ago](https://wordpress.org/support/topic/form-submission-error-8/#post-14549559) * [@wpmudevsupport12](https://wordpress.org/support/users/wpmudevsupport12/) I updated the mu-plugin, and can now access Forminator’s settings through my WP admin panel.
