Confluence Loads with 500 Error after Install
Asked by Chris G_:

Hello. I've been trying to install Confluence with zero luck. I keep getting the following error after the step to set up the database shown below. I checked the logs and not helpful as it just has the same message:

**Description** The server encountered an unexpected condition that prevented it from fulfilling the request.

**Exception**

I have seen this error before on a few occasions. The most common one was missing permissions for the database. May I suggest you check the following:
> 1. Database user permissions
> 2. Ownership of the said database

The database user must have the write, read and create permissions on the database. The user must also be the owner of your database.

Here you can find more details on the database setup for Confluence:
> * ++***[Confluence - Database configuration](https://confluence.atlassian.com/doc/database-configuration-159764.html)***++   

Let us hear from you, Chris!
