Nevermind it's been resolved, It was an outdated theme template error and I removed the broken source and it fixed it after the site was cached via Cloudflare 😉
So now the plugin is disabled and custom block is working again 🙂 Well for now till V5 comes ahahhaha
SOLVED
Turns out that I even forgot that I had cloudflare hotlinking enable 😞 Dopppppppp and so I can disable or allow links. I just disable it as it's an easy option but left hotlinking in the CPanel enable with PNG allowed 🙂
Works now as it should, happy days. Also did a bulk email test that got sent to two emails and flying colours with 10/10. Downside that I can't send all 250 or more emails at once on my sendgrid basic account ;( But I'm more focus on emails that work for people to get that allow them to do what they need to do rather then newsletters.
