Dashboard half-loaded + SalesAnalyzer page crash

[netscaline]

Hello,

I've installed the latest PTM-2.8.4 and have 2 issues :

1. the dashboard loads only the upper-half
2. clicking on the page SalesAnalyzer throws an "error occurred while processing your request. Request ID: 0HN2PBG24758F:00000001 Cannot convert null to 'double' because it is a non-nullable value type"

I provide 2 screenshots and tell me if you want me more information, logs, confs...

Cheers Lorenzo
