I do not use AlwayShowMetadata, but the 2 other plugins are installed on my Piwigo 12.1.

Some exif are displayed.
Open StreetMaps is running correctly except for a strange bug : for geolocations made after the update, the map is not displayed on the picture page (either with Modus or Bootstrap darkroom). Even if the pin of the photo appears on home and album pages. If the geolocations were specified before version 12 of Piwigo they are correctly displayed on the picture page.

Example
geolocation made before v.12 : https://gabandjo.legtux.org/piwigo/pict … 2-bretagne
geolocation made after v.12 : https://gabandjo.legtux.org/piwigo/pict … aint_armel
