# WordPress database error

 * I’m trying to write my own little plugin and I have tested it on several of my
   WP, but when I installed it on my last WP (the one I really want to use it) I
   got this message:
 * > WordPress database error: [Too many keys specified; max 64 keys allowed]
   >  ALTER
   > TABLE wp_Counterize ADD INDEX ( timestamp );
 * I don’t think it has any thing to do with my specific plugin.
 * Anyone know what to do?

 * You’ve hit a [limit on the number of keys allowed by the MySQL server](http://mike.kruckenberg.com/archives/2006/06/limit_on_number_1.html)
   you are trying to use. That is, you are using too many indexes. You can change
   the value but only recompiling MySQL. Unless you have the ability to do that,
   or can talk your host into it, you are going to have to rework your indexes probably.

 * I have no Idea I’m only a user.
    My plugin is not establishing any new tables
   in the database only looking into 2 tables.
 * Is it the plugin mentioned in the error (Counterizeii) that is establishing the
   error?
    or is it a coincident? (order of plugins installed)?

 * I had assumed that the plugin named **was** your plugin. Disable Counterize and
   see what happens.

 * if I deactivate Counterizeii or any other plugin and then activate my plugin 
   nothing happens – meaning no warning occurs.
 * It is only a warning all the plugins seems to be working

 * I have addressed this problem on Counterizeii webpage
    ( [http://www.navision-blog.de/counterize-ii-english/](http://www.navision-blog.de/counterize-ii-english/))
   and they have now found a programme error. _“The problem is a small typo in the
   file “counterize\_install.php”. If you open the file and you go to the end you
   will find twice something like: if($minorVersion < …
 * you have to change them to:
    if($MinorVersion < …
 * please note the “M” of “minor” now capital.
