I've come back to Zenphoto after using very,very early releases (think 2008). Did install from download.

WARNINGS & ERRORS:

How doI change is one?

MySQL version 5.1.56
Warning!
MySQL Version 5.0.7 or greater is required. Version 5.5.0 or greater is preferred. Use a lower version at your own risk.

this I cannot change

Database credentials in configuration file
Error!
MySQL reported: Access denied for user (I changed IP for this posting)'admin'@'00.163.128.0/255.00.00.0' to database 'zenphotos'

What's wrong?

Fill in the information below and setup will attempt to update your configuration file.

I used the host and db name from long ago, possibly hoping the pictures will reappear (as a test, I want to start new album)

Except the last one there are no errors but just warnings as the notes say.

Regarding the last please look at /zp-data/zenphoto.cfg.php to see if the file is setup correctly.

Database credentials in configuration file
Error!

MySQLi reported: Access denied for user 'administrator'@'69.163.128.0/255.255.128.0' to database 'zenphotos'

The "fill in the info..." disappeared but this error is left. I know the others are warnings that I'll ask my host about.

Regarding the warnings, my versions are from my web host.

PHP Version: 5.3.13
mySQL server: 5.1.56

Are they okay?

The notes are a bit mislabeled and no realy warning. It should all work although we test on those recommended new versions primarily.

Regarding the mysql eror which is an error: Did you check the config file as I suggested?

CREATED! There were 4 or 5 image files that I was told to delete but kept being told they existed afterwards but setup proceeded. Admin account created. I'm now going to see what's in store.

Problem was created by my database and database hostname not being associated with each other at my web host end. (My paraphrasing).
