Hi, Fotis. It turned out to be an issue with my DNS records in Cloudflare and has been resolved. I don’t understand why files with underscores were playing and files with spaces weren’t, but I’m glad it’s sorted. I will leave a review. Thanks again for your help.
Thanks, Fotis. I’m now thinking this issue started when I implemented CloudFlare. I will do more investigating. I appreciate the quick and helpful reply 🙂
