Plesk: Test Directory located in /httpdocs/test/

by

0

Description:  In default Plesk Installations a folder called Test is created under httpdocs/  this folder contains a series of scripts designed to perform “hello world” type tests to confirm that those scripting languages can be used.

If the test scripts are no longer needed you can remove the directory

If you would like to keep the scripts but prevent access to them, you can either:

1. chmod the directories to 700 and files to 644; or

2. Move the test folder out of the httpdocs/ directory into a non-webaccessible directory for later use.

Symptom: When attempting to add a new mail account you receive the following error message: Unable update mailbox: mailmng failed: Empty error message from utility

Solution: The error is caused by a security update released in Ubuntu for mysql 5.1.66, there is currently no Plesk fix for this error as of Nov. 13th, 2012. In order to resolve the error you must roll back 5.1.66 to 5.1.63.

Instructions can be found here for the temporary fix: Parallels Forum

Note: If Ubuntu 10.04 LTS is set to automatically install updates, every time it checks for updates it will patch 5.1.63 to 5.1.66 again.
