Hi Alberto,
a) set all your CSS tabs in the WebServer procedure to "global defaults". (I'd recommend leaving the checkboxes on unless you need to add something of your own)
b) On the WebServer procedure, Buttons tab, delete all the buttons until they "come around again". (as you delete on it gets added to the bottom of the list.) This has the effect of setting all the buttons back to default as well.
Cheers
Bruce
