The content filter is nothing to do with MODx - it is somewhere between you and the site, either on your PC or your ISP.
I have no idea what words are making that content filter score 947 and put it firmly in "dodgy".
Solution 1: Log in somewhere less restricted.
Solution 2: Change the phrases in the language file to "Fluffy Rabbit", "Something Work Related", "Very Safe Button", "China Is Great" etc.
Thanks For the advise I’ll try that - It’s strange because I’ve always been able to login here at work with no problem.
