Maps suddenly disappeared on my wiki. Why ?

Yesterday suddenly my maps all disappeared from www.heraldry-wiki.com. That is a wiki using the Mediawiki MAPS extension. I am the only editor and did not work at the time on the wiki, so made no changes in the software.

First a large error appeared, by removing all extensions it worked again and by one-by-one adding the extenstions, all work, except that the maps are not displayed. There are no database errors and the update.php runs fine.

Se f.e https://www.heraldry-wiki.com/heraldrywiki/index.php?title=Rosstal where the map does not show, only the script line.

What happened here ? And better how to get the maps back ?
