Hello,
I have checked the issues you mentioned, and I did not observe the same problem. Generally, when you want to edit a page using the frontend editor, you must log in using your user credentials from the front end of your site. Once logged in, you should be able to edit your page. I have attached your home page in editing mode, and I also checked the preview, which appears working fine.
Additionally, I noticed that you have entered an incorrect license key in the Helix3 and SP Page Builder License & Update under the settings sections. Please recheck your email for the correct license key. You can find your license information here: https://www.joomshaper.com/dashboard
Thank you!
