Storefront /Gravity Forms Critical Error

Hi !

Same for me, no response from Storfront support nor Gravity Form support. If you’ll find something, could you explain how you resolve this issue ? For the moment I commented the lines of storefront’s theme in functions.php :

// if ( version_compare( get_bloginfo( 'version' ), '4.7.3', '>=' ) && ( is_admin() || is_customize_preview() ) ) {
// 	require 'inc/nux/class-storefront-nux-admin.php';
// 	require 'inc/nux/class-storefront-nux-guided-tour.php';
// 	require 'inc/nux/class-storefront-nux-starter-content.php';
// }

Line 62 to 67.

But it’s definitively not the good way to resolve this bug but I can now use Gravity Form.

Thanks !

Hi !

I’ve installed a fresh wordpress ( 5.7.2) on wampserveur v3 with php v7.4.9
woocommerce Version 5.3.0
Gravity form Version 2.5.1
Storefront Version 3.6.0
All I have done is install and activate this 2 plugins and theme.

On all submenu of Gravity forms menu I have this error :

Fatal error: Cannot declare class Storefront_NUX_Admin_Inbox_Messages_Customize, because the name is already in use in C:\wamp64\www\wordpress\wp-content\themes\storefront\inc\nux\class-storefront-nux-admin-inbox-messages-customize.php on line 17

I also had this problem but was able to determine the issue.

Turns out I had two Storefront themes installed. Once I removed the additional theme, the problem went away.

This was a project handed to me by another developer so I don’t why there were two themes. He probably just duplicated the existing folder and renamed it. To remove the second one, I just dragged the additional folder out of the themes folder and placed it somewhere else. I’ll delete it just as soon as I am sure there’s nothing there I need like some stylesheet or whatever.

Hey @mahii-conception,

Thanks for the details of your testing.

I spun up a fresh installation of WordPress using Local with the configuration below.

PHP v7.4.1
WooCommerce v5.3.0
Gravity Forms v2.5.1
Storefront v3.6.0

I firstly activated Gravity Forms then activated the WooCommerce plugin with the Twenty Twenty-One theme activated. When doing so there were no error messages displaying on the Gravity Forms sub-menus.

I then activated the Storefront theme. After doing so I then see the error message displaying. So it seems this conflict does only occur when a fresh installation of Storefront is activated on a site with Gravity Forms installed

Looking at the code which the error references it’s for the note which is added to the WooCommerce > Home page which would be this note below.

It seems for some peculiar reason the Gravity Forms plugin is trying to redeclare that note on its plugin pages. When cross-testing no other plugin I tested which have WordPress sub-menus produces the same error message when Storefront is activated.

The theme added notices in two places for the Storefront setup. If WooCommerce is enabled a notice would only be displayed within WooCommerce > Home like in the screenshot above which is classed as the WooCommerce Admin Dashboard.

If however WooCommerce is not enabled Storefront would display a different notice at the top of each page. Below is an example of that.

Interestingly the only page on the site where this default WordPress admin notice does not display is on the Gravity Forms page. It seems Gravity Forms have a custom page that removes WordPress Admin Notices in their plugin.

Instead, the Gravity Forms plugin seems to have a custom notice implementation which refers you to the WordPress Dashboard like the below when a new admin notice is present on a WordPress installation.

It seems to be this custom admin notice implementation within the Gravity FOrms plugin that is causing the issues with plugins or themes that add notifications to the WooCommerce Admin Dashboard.

This is tricky as Storefront is not doing anything out of the ordinary with the notices and it’s only the Gravity Forms plugin that is showing this error. I’d suggest initially reaching out to Gravity Forms to they an offer with their thinking relating to this.

For reference going through the Storefront setup process removes the admin notice and the error.

I hope this helps.

Hi @mahii-conception,

Glad to hear that and thanks for confirming that Stuart’s solution worked for you!

@bruceinct could you please confirm if Stuart’s solution works for you too?
