Hello Toufiq,
I just updated SP Page Builder to 5.4.0 and am getting the same error. I don't think it makes much sense to create separate posts for te same problem because it is clear that it is related to the latest version of SP Page Builder.
I think it would be more productive to everyone, and specially for you and your team, if you explined what the problem is and provided a link to the patch that we all could download and install. This file could also be available in the Downloads menu.
I need to present some layouts updates by tomorrow and, for the moment, I'll do the same as Shawngela Pierce and sandymikami did above: reinstall 5.3.8.
Please, provide a 5.4.1 version with this fix.
Best regards,
Diego
