Customizer is not working


the Customizer Tool is not longer working at all. I made an update today, but it didn´t change anything in that case. If I click the customizer button there´s always a blank page and nothing happens. Other themes seem to run well. Could you please help me to get along?
Thanks and best regards, Tanja

Hello Tanja,

Can you please try to temporarily deactivate all your plugins except Sydney Toolbox and Page Builder by SiteOrin, and see if it helps?

Kind Regards, Roman.
