Hi there,
I’ve refreshed https://www.vrajfresh.com/delivery/product-category/grocery/ and it does work intermittently – Sometimes I get the same error as outlined in your screenshot and other times the content displays as expected.
Given the intermittent nature here, you’ll definitely want to get in touch with your hosting provider to ask for server error logs. It’s possible that this is linked to memory timeout issues, caching, permalinks, CDN or something else entirely. Once you have those error logs, please paste them here and we can take another look into things ??
For more reading on this, have a look at the following resources:
Thanks!
