 * After updating eShop from 6.3.5 to 6.3.7 on WP v3.5, I began receiving errors
   in the dashboard as follows:
 * > Warning: call_user_func_array() [function.call-user-func-array]: First argument
   > is expected to be a valid callback, ‘eshop_orderhandle_process’ was given in/*
   > path-to-wp-install*/wp-includes/plugin.php on line 487.
 * Rolling back to 6.3.5, the warning disappears. Only other plugins activated are
   Akismet and Google Analytics.
 * Site is [http://beccayoderart.com](http://beccayoderart.com). Errors won’t appear
   because I’m back on eShop v6.3.5, and they’re only showing to logged-in admin
   users.
 * Others are apparently having the same issue:

 * then why didn’t you follow up on the Quirm? or are you not using multisite?
 * I have already answered saying I will look at this on the weekend.

 * I’m not a member of Quirm.net, and I’m not using multi-site. Thanks for the attention
   to the issue. We’re still operational on 6.3.5.

 * If you are seeing this error, please indicate on what page(s) it occurs. Otherwise,
   we may not be able to replicate the problem.

 * Can you replicate the problem using the default theme with **all** other plugins
   deactivated? At the present time, we cannot replicate this on any of those pages.

 * I recreated the problem on a test site using same content and imported MySQL 
   db, same plugins, same theme. Then I disabled all plugins other than eShop, tried
   the default themes (twenty-twelve, twenty-eleven, twenty-ten) one by one, and
   the error persists…
 * How can I be helpful?

 * No – try a completely fresh single install. No imported content, no imported 
   database. And definitely no multisite.
    So far this issue can only be replicated
   in multisite installs.

 * 6.3.8 released to fix this for multisite installs. In theory if you had this 
   issue it should now be resolved.

 * Wow, quick work! I’m not running multisite, but I can verify that 6.3.8 fixed
   the issue on my two test sites and the live site that were *all* showing the 
   same error. Thanks for your fast response.
