WiscWeb - Can’t edit blocks in UW Theme 2.0

This document walks users through what to do if they try editing their page in UW Theme 2.0 and they aren’t able to add, delete, or modify blocks.

Issue

Users will not see the option to edit blocks. In their block inserter window, the message will read “No results found.” 

If a user is experiencing the block visibility issue, the Blocks panel will show a "no results found" message.

Also, users will not be able to add new blocks by using the slash (/) option. 

Cause of issue

The reason this is happening is likely related to Gravity Forms. 

Gravity Forms has a few options in their “Embed Form” fly-out that seem to disrupt the typical behavior of blocks within our environment. Particularly, these two options: 

  • Add to existing content (page or post)
  • Create new (page or post)

Gravity Forms offers three options for embedding forms. The first two options - Add to Existing Content and Create New - are highlighted in a red box.

WiscWeb disables the Gravity Forms block because it gives the impression that you can edit a form within a page, which is not possible. Instead, we drive users to the Shortcode solution, which is more inline with the experience users had in UW Theme Classic and results in less confusion overall. 

When embedding a form on your page, WiscWeb recommends using the the third option in the Embed Forms flyout titled "Not Using the Block Editor?"

Since we disable the Gravity Forms block in WiscWeb, the two other embed options will not work as expected and result in users losing their ability to add blocks to a page.

Steps for fixing the issue

Short term solution

The best method for fixing the issue in the short term is to delete the “gfAddBlock” key from your browser’s local storage: 

  1. View one of your webpages in your browser (not the editing view but the front-end, public view)
  2. Open your browser’s inspection/developer tools
    1. Right click on the page
    2. Click Inspect
  3. Locate the local storage:
    1. If in Firefox, select the Storage tab
      1. Select Local Storage
    2. If in Chrome or Edge, select the Application tab
      1. Under the “Storage” heading, select Local Storage
  4. Find the key called “gfAddBlock”
    1. Right click on it
    2. Select “Delete”
  5. Return to the editor and confirm that you can see blocks in the Block Inserter (Plus icon at the top left of the editor screen)

Long term solution

In the long term, we recommend discontinuing use of the “Add to existing content” and “Create new” options that appear within the larger “Embed Form” flyout. Instead, use the “Copy Shortcode” solution and paste the shortcode into a Shortcode block on the page. This will prevent the issue from recurring.
