Hi @anon7878, thanks for reaching out!
I take it your DMS and CRM are WordPress-based plugins? If that’s the case, it sounds like a false-positive is blocking their crons (or other background actions that affects them). Firstly, I’d disable Wordfence just to make sure the message doesn’t remain regardless and another configuration issue is the cause.
If it disappears/reappears depending on the status of Wordfence, I would enable Learning Mode. https://www.wordfence.com/help/firewall/learning-mode/ also includes a method for checking for blocked action(s) in your Live Traffic page manually if Learning Mode is ineffective. Sometimes the Live Traffic method will show you precisely what is being blocked and by which rule/setting.
Let us know what you find out,
Peter.
