 * Hello!
 * I’m using WordPress and WPForms-Lite on a localized Ubuntu 20.04 web server. 
   I can create the form, and add the block. When I select the form I created from
   the pull-down, the error “Error loading block: Invalid block.” appears. Nothing
   is added and nothing displays.
 * Any ideas on how I can resolve this?
 * Thanks!!

 * I’ve just re-checked and everything works fine on my tests.
    I guess it may be
   theme/plugins conflicts. If it is possible, try to activate a default theme (
   e.g. Twenty Twenty-One), deactivate 3-party plugins, and try again.
 * P.S. Don’t forget to make a backup for the database before.
