This could be based on your storage usage as you are at ~ 80% its possible that the install requires tmp storage.
Based on this I have increased your storage for you to see if that helps.
I can see you are using most of your disk space for your main WP site. Since this usage is true to the domain and your site I have increased your storage space for you.
You are using CF for your DNS and not our NS. Therfore, you will need to setup the MX records at the CF dashboard.
You should setup the MX record for yourdomain.com pointing to the A record for mail.yourdomain.com that you are required to assign pointing to the IP here 198.91.81.13

Your IP is indeed flagged on multi accounts despite you stating otherwise.
