I was looking at the documentation for printAlbumMenu and while it talks about the $firstImagelink variable, I don't see it anywhere in the plugin. It doesn't work when I set it to "true" either. Can anyone help me with this?

Did you enable the plugin ?
Also have a look at zp-extensions -> print_album_menu.php.
That's where the function printAlbumMenu() comes from.
The file is very well commented.

I realized that the plugin was old, as my copy of print_album_menu.php didn't have it. Now I'm having database issues in trying to upgrade ...

MySQL Query ( SELECT * FROMzenp_administratorsWHEREvalid= '1' ) failed. MySQL returned the error Unknown column 'valid' in 'where clause'

I ran upgrade.php as well, but the same error comes up.

I dropped zenp_administrators and it worked.

If anyone else has this problem, please run .../zp-core/setup.php?debug which will create a setup log of the SQL statements of the upgrade. Apparently the one which adds the valid field to the database is failing. We will need this log to understand why that happens.

I am having that error and here are the contents of the log file:

This is the log of just the beginning of setup--no SQL statements have been executed. So has the error occurred at this point?

Yes it has. I also get the following warning at the setup summary screen before that:

You should consider porting your data to UTF-8 and changing the collation of the database fields to utf8_unicode_ci and setting this true. Zenphoto works best with pure UTF-8 encodings.

What version of zenphoto were you upgrading from?

I believe it was 1.2.5, perhaps 1.2.5 RC2

Thanks. I have found the problem. For any one else with this problem, you must either not skip so many releases or install with the nightly build. The 1.3.0 release became dependend on a change to the database introduced with the user=groups plugin that was introduced in the 1.2.6 release. We do not test upgrades from that far back, so missed the dependency.

If I understand correctly, installing the nightly should take care of it?

Please, disregard the question. I tried it and that seems to have fixed things. Thank you so much

Just a quick FYI, I just finished upgrading from version 1.2.4 [3716] -- and I ran into the same problem. Installed the nightly build 1.3 [5577] just now and it works fine. Looking forward to the next incremental release so that I be on an official build.

If you would rather be running one of the "official" releases, just reinstall v1.3.0 now. The problem was "permanantly" fixed when you installed the nightly, so reverting will still work.
