Now i'll hold my hands up and say i have no real knowledge of childthemes.
I have one on both my sites one ver 3.2.1 and the other 3.3.
Today i made some changes to the step2.php on both sites.
On the 3.2.1. site i was able to move the php into the childtheme and when testing everything runs ok. However on the 3.3 one i get an error when doing the same.
Can someone in the know advise on what to do please
