Getting the same thing after an upgrade to 3.0 from 2.17.1:

Overview of goals and viewing individual goals works fine.

I got this response from support which fixed the issue for me:

To answer your question: We haven't seen this error in Piwik 3 before. It sounds like there is a column "description" in the "piwik_goal" MySQL table missing. Can you or your system administrator execute this MySQL query and check if it works afterwards:

Solution: run this SQL query

ALTER TABLE piwik_goal ADD `description` VARCHAR(255) NOT NULL DEFAULT '';

@tipmaster thanks, that was definitely the problem. I guess the db upgrade missed a step (or maybe skipping a piwik version skipped a db migration).

I had the same issue, now it works after altering the table, thanks @tipmaster !

Having the same fatal error message too!

We had the same error.

Piwik just told the administrator:

oops, an error occured ... contact your administrator

Nothing more. Only a 500 error in the access.log, but no more specific error message.

The solution posted by @tipmaster did also solve the problem for us. It seems that goals that were created in Piwik 2.x did not have the "description" column yet, which causes the error in 3.x
