“No articles in shop. Please rebuild cache.” – not working

So yesterday I updated spreadplugin to latest version and my shop disappeared. (from 4.7 something to the latest presumably).

I see this a recurring issue here, with some saying updating solves it. Not so for me…

We do not run any cache plugins and the WP version is 4.9.20 and the spreadplugin is 4.8.6. Spreadshirt shop is still functional on their end, nothing was changed in config for spreadplugin and pressing that darn rebuild cache button (“Cache neu erstellen”) does nothing apart from printing:

Rebuilding Page 1 of 1…

Done

Successfully stored page 1

Spreadshirt seems to work (though it’s not showing ALL items when you have ALL items selected – I guess that’s a spreadshirt issue… https://tjjk.myspreadshop.net/)

We use use the spreadplugin code on the page https://trondheimjujitsu.no/profilshop/

Shop id is 547222
