Looks like you got past the part where it creates the tables, so I would guess the permissions are OK.

Looks to me like there is a problem with the username you used when you did the installation. All the fields related to username are empty in that error you pasted.

topic_poster,              ,  <-- why empty?

topic_poster_name,       '',  <-- why empty?

topic_last_poster,         ,  <-- why empty?

topic_last_poster_name,  '',  <-- why empty?

 

None of those can be null. So, did you do something weird when creating the username, or use a weird character, or are you using integration with an existing user or maybe a display name plugin?

Something is going on with the username. It’s not present, so the INSERT failed.
