HTTP Error 500 on setup page 5 (The Look)

I’m getting an HTTP ERROR 500 on ‘The Look’ segment of my journal set up pages on ojs 2.4.8.1
How do I fix it?
I have tried different browsers.
I have cleared cookies and cache.
I am a doctor with minimal software or coding knowledge.
My OJS is hosted on Godaddy using managed wordpress and they recently upgraded the wordpress software to version 4.9.6
My website is http://rhime.in/ojs
Please advise.
