When I log into the admin panel I get this error at the top, Fatal error: Class 'Magpleasure_Filesystem_Helper_Data' not found .../app/Mage.php on line 546

and i can see any menu?


 public static function helper($name)
        $registryKey = '_helper/' . $name;
        if (!self::registry($registryKey)) {
            $helperClass = self::getConfig()->getHelperClassName($name);
            self::register($registryKey, new $helperClass);
        return self::registry($registryKey);
  • The error is that the file "Magpleasure_Filesystem_Helper_Data" is missing, did you install an extension recently?

It's very possible that your shop was hacked last night!

Check for new files from last night in your extensions folders, install Secuirty Patch SUPEE-5344 and rename your admin folder.

Affacted systems shows new users with admin permissions.

@Dashpuppy Jason:

  • Remove all files: app/code/community/Magpleasure/Filesystem/
  • Clear your cache, login should be possible now.
  • Check for new "Admin Users"
  • Patch your System with SUPEE-5344!
  • Do you have any actual proof for this FUD?

  • Yes, many customer complaints about broken / hacked magento systems. We have a list with similarities of affected shops in our blog: New extension was installed last night, SUPEE-5344 is missing, BruteForce on /admin/ folder and new files in the downloader cache with the same timestamp. ;)

  • Really? Customers never learn. Who still keeps their downloader folder world wide open and a default admin path. I read the blog, looks solid. I remember this vendor from a while back though. I'll have to search our ticket system, maybe the name is slightly different.

  • Heise Security has also an Alert online: heise.de/security/meldung/… I think it is related to: blog.checkpoint.com/2015/04/20/analyzing-magento-vulnerability

  • Clearing the cache folder didn't quite work for me. See magento.stackexchange.com/questions/65097/… for a better solution using a CLI tool Commented Jun 3, 2015 at 0:59

It is because you call helper of a module you have not enabled.

Check Magpleasure_Filesystem mobule please.
