I haven't done any manual CSS edits or HTML edits to any file. Only in Style.css I added a new line to change the background of the widget color from white to green.
Now today I see the theme has a update, I update it and I go to my main page: http://www.interviewedyou.com
And see all color changes I did are gone! That the theme is not anymore as I made it be.
I smart made a backup and just moments ago restored it.
You are now seeing the edited version the correct theme I want to maintain when upgrading.
Under Visual Effects - Theme selection - I choose the light green theme and made to that certain theme all the oclor changes using
Theme skinning option and all that other stuff.
So how can I update my theme without losing all the color changes I did?
