I'm using the JEM Modul-Calendar 2.2.3 at Joomla 3.9.3.
For me everything seems to work fine at any browser - i can move back and force one month or year by clicking the arrows, since one of our users told me he could not navigate in the modul. The pointer changes from arrow to pointing finger, but if clicks an arrow nothing happens. I won't belive it since i could reproduce the error on a different computer - he's right!
In the browser console i can see:
Quellübergreifende (Cross-Origin) Anfrage blockiert: Die Gleiche-Quelle-Regel verbietet das Lesen der externen Ressource auf https://amateurfunk-im-alstertal.de/?option=com_ajax&module=jem_cal&format=raw&Itemid=101&modjemcal_id=144&modjemcal_month=4&modjemcal_year=2019. (Grund: CORS-Kopfzeile 'Access-Control-Allow-Origin' fehlt).[Weitere Informationen] 2
sorry, german OS
So i included
Header set Access-Control-Allow-Origin *
to the .htaccess and everything works fine.
But now i'm afraid i opend an insecure door
Is there a better way to solve this problem?
it all happens at one site .
Maybe it is relevant, that this site is migrated from Joomla 2.5 without ssl and the old Eventlist installed.
I don't know what's going on there
