when I select the image option from the site title dropdown in the customizer, the whole site just disappears, i.e. goes white. Not just in the customizer preview, the problem persists when i save the option and publish the site. When the text option is selected, everything works fine. This is a problem that that occurs on two of our websites ( http://amalia.testtest.net and https://josephundsebastian.com), a third site, however, has no problem with it. We tried disabling all scripts we use, no effect. There is no plugin we use on both malfunctioning sites. We can't seem to figure this one out on our own, please help.
Thanks in advance
