i am getting this error message in my apache server logs:

File 'c:\mysql\share\charsets\?.conf' not found (Errcode: 2)
Character set '#33' is not a compiled character set and is not specified in the 'c:\mysql\share\charsets\Index' file

my server configuration is as follows:

php 4.3.11, apache 2.0.54, windows xp, mysql 4.1.12, activestate perl 5.8.6, phpmyadmin 2.6.2

mysql is installed in:

c:/program files/mysql/mysql server 4.1

does anybody know the cause of the error and how to fix the problem? it shows up whenever somebody accesses a php page, such as phpbb forums. the error doesn't seem to cause any problems with the php pages (at least not any that i have discovered...yet), but it is really troublesome having thousands of incidents of that particular error in the apache server error log.

any help would be much appreciated
