Thank you for your reply Peter. I understand the caching concern but not the HTML filtering feature. Just to clarify, I can view the code with “PHP and “Frontend” selected, make the change directly in the HTML editor, select “Update,” and I get a “post updated” confirmation. If I go back to the main Lazy Blocks tab and immediately go back into the page I just edited, the change didn’t save. Does that still sound like a filtering issue?
