I’m trying Page Category Plus 1.1. with WP 2.3.1 german-edition. When choosing the <"Verwalten" (should be something like "Manage" in English) -> Page Category Plus> -options I’m getting the following error message:

WordPress database error:
[You have an error in your SQL syntax; check the manual that
corresponds to your MySQL server version for the right syntax to use
near '-blog' at line 1]
SHOW TABLES FROM mydatabasename-blog

This seems to be due to the fact that I’m using database-names containing hyphens, which has caused no problems so far with wordpress or any other plugin.

Thank you for your answer, Andy. My "config.php" has the following line:

define(’DB_NAME’, ‘mydatabase-blog’);

WordPress: 2.3.1 (de)

PHP: 4.3.10

MySQL: 4.1.10a

I’m getting this error in nine WordPress-Installations which are all hosted at a Virtual Server with SUSE Linux 9.3.

Any more ideas?
