Summary
In weathermap-cacti-plugin.php, the liveview case fetches a single row:
$map = db_fetch_row_prepared("SELECT wm.* FROM weathermap_maps ...", [$id]);
if (cacti_sizeof($map)) {
$maptitle = $map['titlecache']; // correct flat access
// ...
$mapname = $map[0]['configfile']; // BUG: $map is flat, not array-of-rows
}db_fetch_row_prepared() returns a flat associative array. $map[0] is null. $mapname is null. $mapfile becomes $confdir . '/' (the directory itself). The WeatherMap engine then tries to ReadConfig() on a directory path. Liveview silently renders nothing.
This is an old-style $map[0][...] pattern from before the Cacti migration that was not updated.
Fix
Change $map[0]['configfile'] to $map['configfile'].
Priority
Hard failure. Queue for Friday.
