Pagebuilder code gets stripped in frontend

Hi!

I have a strange thing happening on all of my sites where I use page builder.
When I am logged in in frontend and edit an article, I see my pagebuilder and can edit it.

After I have saved it and click again on "edit ardicle", I don't see the pagebuilder "framework" anymore. I see all my page content in my custom editor (not matter if TinyMCE or JCE is used) and the "switch to page builder" button above.

After that, even in backend the article is not a "page builder article" anymore...
I assume, that all the pagebuilder code gets stripped from the html code, that would explain why I can open an article one time...

About my setup:
I am logged in as Super administrator and have no filtering enabled in Joomla, use protostar template and tested in Joomla 3.7.5, 3.8.0 and 3.8.1 with PageBuilder 1.5.5 and 1.5.7. All setups give the same result.
When I use the versions and restore the previous version of the article, it is loaded with page builder again...

Can you reproduce this issue or know how to fix it?

Thanks,
Tim

Hi
I have reproduced the issue ...
I'm surprised that you have the same behavior with older versions. I will check that

Ok, glad you're working on it. Thanks!

if you click on the "switch to PB" button, you should get your interface back with all your elements. Right ?

Yes You are right ...
Ok that means the code is not lost, but it's still kind of weird, especially for some of my customers . Will you try to fix it?

Cheers,
Tim

yes, I'm trying to find why this occurs, as it was working before
