Portal Themes: Button background color inactive
since implementing a Support package stack into our customers' EP (NW 7.30 SP12) buttons in the head area of travel management screens have no background color anymore. For the customer theme has a grey main background color, it's quite hard to decide which button is active and which not.
Before the implementation the buttons had a "yellow" color (see attached before/after screenshots).
We've already followed the notes 1982735 and 2028300 - and tried to change the color and change it back again - tried to reimport the customer theme - nothing helped us so far.
Do you have any idea how to solve this problem?
Thanks & regards
