Yesterday I was trying to solve a nasty bug and had to swap themes to the default twenty eleven for a second.
This had the effect to change the default size of thumbnails and also to remove the mouseover shadow effect as well as the rounded corners of all thumbnails besides the featured ones.
not sure what to do or how to re enable that as I don t see why after having re-enabled the theme the settings are not the same.
Is there a manipulation in the ACP I need to do or is this an isolated incident I need to troubleshoot myself?
What could have changed by changing to another theme and then back regarding thumbnails besides the size defaulting back to 80x80?
