500 internal error after upgrading the PageBuilder plugin Version 2.3.1

Hello there !!

Here is my probleme : I can’t have access to my web site after upgrading the page builder Version 2.3.1.

I disactivated all my plugins, refresh the ‘cache’, and reactivated each plugin at once.
When i reactivated page builde plugin, i have an 500 internal error.

Do you know where the probleme could come from ? I tried to reinstall the page builder after downloading it from you web site, but still the same probleme.

My WordPress version : Version 4.4.2
Page Buidler prb : Version 2.3.1
My url : http://www.pascale-boudeville.fr/

Thank you so much for your heeeeeelp !!
