We are using SugaCRM 9.1(Professional version). when Go to Home tab and click on the "My legacy Dashboard" i am not able seeing the dashboards but it is showing a blank page.
Double check if there is any js error at the console tab of DevTools (press F12 on Chrome or Firefox).
Additionally you can download the sugarcrm.log and look for some suspicious error.
Finally you can download the php error_log from SugarCloud Insights at Admin page.
