# Plugin Activation causes Empty Response

 * I’m working on a client site that was set up by another developer (which is why
   I can’t update it to 3.2.1). However, I’m now running in to a curious issue.
 * Whenever I attempt to activate the Relations Post Types plugin, the site fails.
   Instead of seeing the dashboard or blog front-end, I’m presented instead with
   an error page for an “empty result.”
 * I can deactivate the plugin just fine via FTP … but I can’t get things working
   without this plugin!
 * I’ve also tried testing this locally on my machine, on my personal production
   server, and on a friend’s VPS – the plugin works everywhere else.
 * I tried looking in the Apache error logs … but they don’t claim anything’s wrong.
   Where else can I look to diagnose this problem?

 * OK, I’ve tried testing locally again using older version of WordPress. It seems
   anything in the 3.1.X branch suffers a memory problem during activation of this
   particular plugin. Not 100% sure why … but it’s annoying.

 * Finally talked the client into upgrading to WordPress 3.2.1, and now it works.
   For the record, this seems to be a recurring issue with the 3.1.X branch … if
   you run into it, **upgrade**.
