If you want to revert all to the default, go to the skin folder/panels/ and delete or rename the intro panel.xml and intro panel menu.xml
+ go to the skin folder/graphics/ and delete the 'main menu folder'
+ go to the skin folder/graphics/boxes/custom and delete the 'main menu' folder.
Thank you, will take a look at what it can be.
If you click on "Staff Feedback", there will be buttons with the player statistics as always. The thing is that I have "Stats" tab set as the default one in this specific widget. That means every time I open the already played match, the first thing I see is the Stats tab.
If you would open the 'match full time review panel.xml' file in the panels/match and locate line 272, there's a note about were to change the default tab.
