404 error on editing siteorigin pagebuilder

I’ve seen there have been other people have this issue over the years with the pagebuilder plugin. I have deactivated all plugins and even when I clear cache and even when I have only the siteorigin pagebuilder activated it still gets the 403 error.

Using Vantage theme (isn’t this by Siteorigin?) with siteorigin pagebuilder and widgets bundle.

I’ll test a default theme but at this point, I suspect it was due to upgrading the WP core or the plugin. It’s definitely a siteorigin plugin issue as it happens when only this plugin is active.

At this point I’m looking at restoring the site back a few days before recent updates.

Would like to be able to update though…

Thanks
