# PHP Error message

 * I am seeing this error in my wp-admin/error_log
 * `PHP Warning: call_user_func_array() expects parameter 1 to be a valid callback,
   class 'PAnD' not found`
 * This shows up at roughly 2 minute intervals and began on 10/14/16, which is the
   date that several upgrades to the plugin were pushed out.
 * I disabled the plugin, waited 10 minutes, and the error went away.
 * I reactivated the plugin, and the error resumed.
 * I disabled the plugin and the error went away again. It has not resumed in 20
   minutes since I last disabled the plugin.
 * I didn’t notice any other performance problems, but I am concerned about the 
   error message, so I am reporting this and also keeping the plugin disabled, as
   the plugin is not necessary to site function (but a recurrent error message is
   worrisome)

 * Hi, that is odd. Can you please login to the plugin folder via FTP and check 
   if there is a folder called vendor nor not? The londer structure should be like
   this: [http://puu.sh/s3MMP/1ac8ca9596.png](http://puu.sh/s3MMP/1ac8ca9596.png)
 * Make sure you have the vendor folder. If you do see the vendor folder, please
   dig inside it so see if there is a php and js file present or not.
 * /vendor/persist-admin-notices-dismissal/ => this path should have 1 php and 1
   js file. let me know if you see that or not.

 * Yes, there is a vendor folder, and that path has two files:
 * persist-admin-notices-dismissal.php
 * dismiss-notice.js

   should fix the problem you are facing.

 * Yes, it did fix the issue – I updated & reactivated several hours ago and have
   not seen anything in the error logs, so all is well now.
