Crashed and now settings reset

Hiyas

I crashed earlier and when I came back all my settings had reset, including the 'newbie tips".
Went into preferences and changed everyone back to what I prefer (particles at 4096 not in my lifetime) but seriously how do i turn off the blue popup box. Everytime I do something it's pops up now: inventory-this is your inventory, teleport-you have just teleported etc.

Also I used to be able to turn off certain popups...now my do not show this popup box is empty and I can't add anything to it.

Thanks for your help

*hugs*
