@foxriver76 Thank you. Now I understand what this Plüral means :) I didnt get this and just tried it out. @BBTown ich hatte auch im deutschen Forum gefragt (https://forum.iobroker.net/topic/26223/temperatur-zeigt-bei-1-grad-kein-gradzeichen), aber nie eine Antwort bekommen - und habe gerade erst gemerkt, dass ich versehentlich zwei Accounts hier hatte (den "deutschen" hatte ich auf dem Handy angelegt, den hier auf dem Laptop). Den einen Account habe ich jetzt gelöscht.

@Bluefox I do struggle with the following instruction: "replace index.html and edit.html replace files in /opt/iobroker/iobroker-data/files/vis/index.html and edit.html with files from /opt/iobroker/node_modules/iobroker.vis/www/index.html.original and edit.html.original. Change the file /opt/iobroker/iobroker-data/files/vis/cache.manifest. No matter what, just one symbol to trigger the browser to load files anew. The files must be smaller than 200k. If you have got wrong files, so they are definitly largen than 400k." I understood .. Replace the following two files /opt/iobroker/iobroker-data/files/vis/index.html & /opt/iobroker/iobroker-data/files/vis/edit.html with /opt/iobroker/node_modules/iobroker.vis/www/index.html.original and /opt/iobroker/node_modules/iobroker.vis/www/edit.html.original. in other words.. cp /opt/iobroker/node_modules/iobroker.vis/www/index.html.original /opt/iobroker/iobroker-data/files/vis/index.html cp /opt/iobroker/node_modules/iobroker.vis/www/edit.html.original /opt/iobroker/iobroker-data/files/vis/edit.html Is this correct ? If yes, in my installation /opt/iobroker/node_modules/iobroker.vis/www/index.html.original and /opt/iobroker/node_modules/iobroker.vis/www/edit.html.original do not exist!

Problem went away after deleting and re-installing jqui widget sets
