Hi,
I’ve got the same problem. I don’t get any errors in the logfile. The console shows
GET https://xxx/dev/checkout/ajaxAddArticleCart?callback=jQuery211…81049764156_1457954844070&sAdd=KR10007&sQuantity=1&isXHR=1&_=1457954844072 503 (Service Unavailable)
But after that:
XHR finished loading: GET “https://xxx/dev/checkout/ajaxAddArticleCart?callback=jQuery211…81049764156_1457954844070&sAdd=KR10007&sQuantity=1&isXHR=1&_=1457954844072”.
When I click the link I get a result back.
In Firefox-Console the answer is:
jQuery21105231256060663151_1457955995905("Ein Fehler ist aufgetreten.\n\n\tBitte versuchen Sie es sp\u00e4ter nochmal.\n");
I deactivated the last plugin I installed - It worked last week with the Plugin, but anyway… - but no change.
Any further ideas? Why did you remove the Developer Toolbar Plugin from the store?
Regards,
Cat.
