Zerif Lite – Latest News images not working properly

Hi folks,

Hope you can help. Some of my Zerif Lite featured images in ‘Latest News’ section are not working. You can see them here… https://www.neo-narratives.com

So some are working, some aren’t!

I read some of the replies to this issue and it suggests adding a line to function.php – where do i find this and how do i do it. Is it necessary as i’m useless with code. Also i checked the settings>media in wp and it’s suggesting thumbnails need to be 150×150 but the ones which are showing are bigger than this.

I’ve tired adding the images which DO work to the articles where the featured images don’t work and this doesn’t work either. At a loss here.

thanks in advance.

Brendan.
