Problem on the CRM home page

Good morning friends!!   Could support me

When entering CRM, on the main page it is displayed in white, it does not show the dashlets that were had, checking the CRM log, it sends me the following line:

"Error fetching relationship from cache project_name_link"

I am using SugarCRM version 6.x (6.5.7).
