I am facing a strange issue on my store all of a sudden. I suddenly see an _ underscore symbol on almost all variables in the backend and even one on the frontend on the checkout page. Pls check the attached image.
We haven't changed anything in the last 6 months nor have we installed any addon except enabling cloudflare CDN which we have disabled again. This has comeout all of a sudden.
Has anyone faced a similar issue and any fix for this?
