I've not long ago posted this on Joomla extensions forum:

I'm here because j2commerce.com is not responding so I can't find out if there are any forums there, so, here goes...My Joomla is 5.3.3 and my J2Commerce extension is 4.0.7 running on Debian 12 on a Raspberry Pi 4 with 8G of RAM.My problem is setting getting multiple currencies in J2Commerce to auto update.I am pulling exchange rates from api.exchangerate.host with an assigned API key. That works fine and the JSON result looks as expected.In Joomla I have a scheduled task set up to run every 12 hours and that appears to be fine:http://api.exchangerate.host/live?access_key=<REDACTED>&source=AUD&currencies=USD,EUR,GBP,CAD,NZD,BTC&format=1Also under WebCron I have:https://<REDACTED>.id.au/index.php/component/ajax?plugin=RunSchedulerWebcron&group=system&format=json&hash=<REDACTED>In J2Commerce:Currencies I have my default currency (AUD) set at 1.0 and all other currencies set at 0.0 - I tried setting the non-defaults to NULL but that gave a MySQL error.My problem is that there appears to be a stage needed between getting the JSON and updating the currencies and I can't work out what that missing stage is.TIA
