 * I’m trying to edit post (this happens when adding a post as well) and getting
   the following error below. This has never happened before and I’m not sure what
   to do here as I need to add a post to the site.
 *     ```wp-block-code

 * The error is caused by the “Spectra Gutenberg Blocks” plugin you are using. I
   would recommend contacting their support forum: [https://wordpress.org/support/plugin/ultimate-addons-for-gutenberg/](https://wordpress.org/support/plugin/ultimate-addons-for-gutenberg/)
