Child-Theme not working after Parent Update!

Hi all,

I use a child-theme of the ‘evolve’ theme on my WordPress site because I have heavily modified / personalised it. There was an update available for the ‘evolve’ theme today which I did, under the impression that it would not affect any of my edits on the child-theme.

However, after the update, both the site and the back-end admin pages would not load (the message “this site is not working” would appear instead. I have since been able to access the site again by changing the theme to the default 2015 theme, and have now discovered that if I select the main parent ‘evolve’ theme, the site still works okay minus all my edits. So it appears to be my child-theme that has gone wrong?

Any suggestions or help would be greatly appreciated!

Thanks
