Hi @stephanieliy,
Thank you very much for your reply.
Excuse me, because my message implies that there is a “fatal error” when installing the plugin, when it is not exactly like that.
The problem in this case is when adding the “donation form” block on a page.
It looks bad, the page gets out of configuration.
The message that appears in the editor (Gutenberg) is “Error loading block: you are probably offline.”
If it’s OK with you, I can record a short video for you to watch.
Thanks in advance for all your help.
