HI,
Same problem here: http://www.nestorortiz.es. After updating my WordPress version and enfold theme, I got a white screen just after the activation of my enfold theme. The only thing I can do to enter my dashboard again is to desactive my enfold theme…

I’ve checked my PHP version on my hosting services and I was using 5.0 after it changed to the 7.3. it worked.

Problem solved! thank you.
