I'm editing the file in
/usr/share/themes/base/meegotouch/libsysuid-screenlock-nokia/style/libsysuid-screenlock-nokia.css
and definitely changing the right part I've double checked that and thats how i did it in the first place doing reboot afterwards and no change to the clock colour although the file has changed like i changed it.
The other thing is that i have in that folder (style) two more docs called the same only with .save at the end (.save and .save.1) when i try to edit them they have nothing in the colour section no f's or 0's changing that also didn't work. any ideas?
