Description

In certain environments, after an upgrade to KnowledgeTree 3.6.x, an issue with permissions on the "var" directory and sub directories results in the following exception error:
<ErrorReport Project="BaobabClient"> <UserReport Short="Exception found [mkdir() [<a href='function.mkdir'>function.mkdir</a>]: Permission denied].">

This also applies to a problem while uploading a document when the message "Initializing, please wait ..." appears at the "Metadata Capture" screen.

How to resolve this issue

To resolve this issue, check the following:

1. The user running the apache server should have correct permissions on the following folder and sub folders: <KnowledgeTree Directory>\var

2. Navigate to DMS Administration > System Configuration > General Settings > Urls > Var Directory and check that the path to the var directory is pointing correctly at your <KnowledgeTree Directory>/var folder

The above steps should resolve this issue on Windows and most Linux installs. For Linux users still encountering a problem, continue to Step 3.

3. Check that the following directory exists: <KnowledgeTree Directory>/var/proxies/nobody

If not, run the following commands from the terminal in order to create and set permissions for this directory:
mkdir <Path to KnowledgeTree directory>/var/proxies/nobody
chown nobody <Path to KnowledgeTree directory>/var/proxies/nobody
