I have recently activated ClodFlare’s auto-minify option for CSS. Anyhow, I have found that for some reason, auto-minify changes: background-color: rgba(0,0,0,50%);
To: background-color: transparent;
Could you anyway please create a supportticket so the coreproblem can be solved on long term, not just by workaround?
If you create one please post the Ticket ID here
