Errors When Changing Permissions From Plesk FileManager
Introduction
In some cases, when you attempt to modify file permissions using the Plesk File Manager, you see a complex error message. This prevents you from implementing the required security modifications on your files. These errors often indicate a problem with a key Plesk utility called filemng.exe. This article describes the reason behind the error and the method of correcting it.
Why Does the Permission Error Occur?
Typical error messages are:
- FileManager:getfileinfowrapper() failed: filemng util failed: Maps a character string to a wide-character (Unicode) string failed
- FileManager:getfileinfowrapper failed: filemng utility failed: Unknown error 0x800A0CC1
These errors happen due to the corruption of the filemng.exe utility file. The utility is a fundamental program that Plesk executes all file operations, including changing permissions. When it is broken, the operation fails and displays debug information.
How to Fix filemng.exe Error?
The most basic solution is to overwrite the damaged filemng.exe with a new and functional one. This process ensures the utility can perform its functions correctly again.
Identify Your Plesk Version
Determine the version of Plesk that is installed on your server. The version is important in order to download the right replacement file.
Download the Proper Utility File
Download the corresponding filemng.exe file depending on your version of Plesk.
Example: download filemng.exe for Plesk 10.x if you are running that version.
Download filemng.exe for Plesk 9.x if you are running that version.
Locate the Corrupted File
Open up the directory in which the corrupted file is located. This location depends on your server architecture, but it is usually one of these paths:
C:\Program Files (x86)\Parallels\Plesk\/admin/bin
C:\Program Files\Parallels\Plesk\/admin/bin
Replace the File
You must replace the current filemng.exe file in that directory with the new file you just downloaded. Just in case, it is best to back up the original file first.
Try Changing Permissions Again
After replacing the file, re-log in to Plesk File Manager and make an attempt to alter the permissions. The error should be resolved, and the operation should be completed successfully.
