The media manager window (not the full page med. man.) went blank after using ~/conf/meta.html to do some styling.
The problem turned out to be related to
In ~conf/meta.html add
<style>
.
.
.
body {
.
.
.
position: relative;
.
.
}
.
.
.
</style>
(This would have let me position other block elements relative to the body.) The fix was to comment out the "body {position:relative;}" line. :-( I can forego getting fancy with positionings, so this is merely an irritation, not a serious problem. But it raises questions: :nuts:
1. I'm curious about why this happens. It is a very unexpected behavior that a change in position status (that actually does nothing of itself) has such an impact on the display.
2. Are there any other oddities about the way Dokuwiki handles positioning or z-ordering that are unexpected and undocumented?
