Hi,
I am suddenly experiencing this same problem. Manager shows only blank page and chrome gives me a 500 error. The site is working but not the manager. Tried clearing the cache manually... Nothing on the server error log. I have just updated to latest version of modx week ago and everything was working fine, not anymore...
Any ideas?
And what does this mean:
For starters, I would empty this table (but don't delete the table itself):
modx_dashboard_widget_placement
Does this mean i should take all the numbers away from the database from the table?
Thanks.

Hi, i got it solved. I noticed that the server was running php 5.4 and switched to 7.0 and cleared cache. everything started working.
