I updated my PC from Windows 7 Pro to Windows 10 Pro and in the process I've had to recreate my Apache server and database. I've recreated the database name with the appropriate user access permissions. When I run 1.5.4 setup, I get this:

Checking the database

About to create database tables...

Begin database table creation
(bunch of green checkmarks)
Begin table updates

Done with table create!

Checking table specifications

No tables are actually created and no error messages are shown. However, I do have an error in my PHP Error log:

[04-Oct-2019 22:26:41 America/Chicago] PHP Fatal error:  MySQLi Error: ( SHOW KEYS FROM `[prefix]administrators`[prefix] ) failed. MySQLi returned the error Table '(database).administrators' doesn't exist in engine in (path)\zenphoto\zp-core\functions-db-MySQLi.php on line 95`

So, it seems to expecting the table to exist but is this before or after it thinks it has created the table?

I got it working. I had to grant the user global privileges instead of just the database itself. Which, it had complete control over that database so I don't know.

As it turns out, it was an issue with HeidiSQL program not saving the database name correctly in the user table. It was saving them as "blah_blah" instead of "blah_blah".

Good you figured it out. Btw I don't know anything about that HeidiMySQL program is and never heard of it
