Welcome to our Community and thanks so much for your first post. When joining us, the websafe and child safe are automatically enabled just encase there are any eager beavers getting online!
We are currently aware of an issue where the settings are not always working via the online account even though it shows that they have changed; I am sorry about that. (This has been logged under fault reference P010053385)
We'll be more than happy to manually adjust them from here if needed though.
What I'll do is pop you a Private Message to go through account security with you and we can go from there. Please look out for the Purple Envelope in the top right of the page and pop me a reply when you can.
