Beaver builder version 1.5.9 is not working for my website either. It results in a continuous loop when adding text or images. I am not able to edit existing text either. I have tried disabling plugins but it seems to be the builder. Please let me know how to resolve this issue. It only began happening within the past few days and I have made no major changes within that time.
Thanks for getting in touch! Sorry I had to split your reply since it most likely is a different issue. Do you mind sharing the site URL as well as temp admin access so we can check? You can use the private reply option below.
