user warning messages keep popping up even after uninstall I have recently disables, uninstalled and removed a few modules from my drupal 7 site but this error keeps popping up no matter what I do, I have researched how to remove them but to my dismay nothing, please help.

User warning: The following module is missing from the file system: admin. For information about how to fix this, see the documentation page. in _drupal_trigger_error_with_delayed_logging() (line 1138 of /opt/lampp/htdocs/drupal/includes/bootstrap.inc).
Most probably the disabling and uninstalling process of the modules didn't went smoothly. According to this help page on Drupal.org:


  Restore the module and actually disable and uninstall it (recommended if possible): First, restore the module to its original location in the file system. Then either go to the Modules page and disable/uninstall it from there, or use Drush (drush dis module_name &amp;&amp; drush pm-uninstall module_name, where module_name should be replaced with the name of the module).


Don't forget to also clear the caches, that "magic" feature also resolves a lot of problems ;)

You could also disable the specific message by using the Disable Messages module. However, I would recommend to try cleaning up your Drupal configuration that are causing the messages.
