Hi Sarah,

I hope you are well today and thank you for your question.

I can see you are using older version of theme on your site so please update it to the latest version of it.

Best Regards,

Thank you for your answer.

However, it’s a child theme, how can I update it?

Thank you

I have updated my theme but I still have the same problem :frowning:

Please clear W3 Total Cache that you are using on your site.

Also this can be child theme issue on your site so to confirm it just temporary use the Sparkling theme instead of child theme on your site. If everything works fine then it’s your child theme issue.
