# I’m having errors with this plugin

 * I’m having trouble uploading a demo content from my theme.
    I ran the debug.log,
   and get the following error:
 *     ```
       [19-Feb-2018 01:40:05 UTC] PHP Notice:  Undefined index: HTTP_USER_AGENT in /home/*******/public_html/wp-content/plugins/cmp-coming-soon-maintenance/niteo-cmp.php on line 1150

       ```
   
 * Then I deleted the plugin, and get a new error:
 * `[19-Feb-2018 02:09:11 UTC] PHP Warning: call_user_func_array() expects parameter
   1 to be a valid callback, function 'cmp_plugin_delete' not found or invalid function
   name in /home/*******/public_html/wp-includes/class-wp-hook.php on line 286`
 * Any thoughts?

 * hello [@travellingwithtania](https://wordpress.org/support/users/travellingwithtania/),
   there is no need to worry about both of the errors.
 * First error is because your server do not post User-Agent, therefore this error.
   –
   I will make a small change in code to resolve this error.
 * Second error is caused by plugin routine to delete the saved options created 
   by this plugin. And this routine is not found which is strange as I tested it
   many times on my end and it works fine.
 * Do you still have that error when deleting CMP plugin? (but no need to test it,
   as it will (should) delete all the CMP user settings).
 * But even with that error, there is nothing to worry about, it will simply not
   delete the plugin settings from your database.
 * Alex

 * Thanks for your help!
    Yes, so I’ve deleted the plugin, tried again (no work),
   and then reinstalled again, but the settings were still there… so I think there’s
   something blocking a complete uninstall on my end, just not sure where!

 * I have looked into the uninstall hook and it might really fail in some specific
   cases.
    Thanks for pointing out both of these issues – I will make sure they 
   are fixed in next update!
 * cheers Alex
