I see this all over this board. I have tried several of the fixes and none seem to work.

The Facts:
File I'm trying to install: plg_jw_disqus-v2.2_j1.5.zip
Joomla Version: Joomla! 1.5.22 Stable
PHP Version: 5.2.14
Web Server: Linux Apache

When I try to install Disqus Comment System I get this error:
JFolder::create: Could not create directory
Warning! Failed to move file.

Unable to find install package

PHP Information:
Safe Mode: Off
Open basedir: None
Display Errors: On
Short Open Tags: On

Session Save Path: /tmp
Session Auto Start: 0
XML Enabled: Yes
Zlib Enabled: Yes
Disabled Functions: dl
Mbstring Enabled: Yes
Iconv Available: Yes
WYSIWYG Editor: Editor - No Editor

Any help or suggestions would be greatly appreciated.

Did you check your permissions?

Yes, logged into cPanel and checked with File Manager. All folders are set to 755. I have never had a problem with installing Components. I have installed SOBI2 JCE Xmap and have had no problems.

Hmmm, Just found this in Directory Permissions

Log Directory ($log_path) /home/public_html/logs/ Unwritable
Temp Directory ($tmp_path) /home/public_html/tmp/ Unwritable

I have checked the permissions and they say 755 also. Is this the problem?

I am also wondering what this means, "Unable to find install package".

I tried upgrading to Joomla 1.5.23 Stable but nothing has changed.

Any help would be greatly appreciated.

Found this fix at Joomla! Discussion Forums
forum.joomla.org/viewtopic.php?f=473&t=598028&p=2426952&hilit=JFolder%3A%3Acreate%3A+Could+not+create+directory#p2426952

1 go to the directory where I installed Joomla.
2 find configuration.php file
3 change access level for this file to 755: it is necessary for the changes to remain
4 open it and Change next lines to:5 than save it.

6 And do not forget to return back the 444 level of access to the file configuration.php

I hope this helps someone...
