Hi Toby-
Thanks for letting us know! I’ve forwarded your IP address to our Cloud WordPress security team so that they can investigate and hopefully resolve the issue.
Here are a couple things you can try in the meantime.
First, try switching to a different browser (e.g. Chrome if you’re using Firefox or Safari or vice-versa).
Second, try disabling any browser extensions that might be running. Sometimes these can trick the Firewall into thinking that malicious activity is occurring.
I’ll update you here when I hear back from the security team about what might be causing the blocks for you.
