Yum Update - Joomla Component install issues???

[cgraham]

I have had Joomla up and running for weeks. However, I have made some changes to my server and can no longer install any components or modules. The message I keep getting is that it can not find the xml file. I have tried several components and have verified that they are the correct zip to upload, but they all result in the same error:

Upload component - Upload Failed
ERROR: Could not find an XML setup file in the package.

Upload component - Failed
/home/httpd/vhosts/domain.com/httpdocs/media/install_44adebe5b4507/

I think this may be related to 1 of the following:

A. Permissions issues
B. Joomla is having difficulty unzipping the file
C. Joomla is having difficulty parsing the xml

Currently, I have the permissions set as follows (to allow for component install):

The following folders are writeable and are owned by apache:apache with 777

media
administrator/components
components
images/stories

I recently upgraded my server to PHP 5.0.4 along with BZip2, libxml, php-xml updates, so I am currently scratching my head trying to figure this one out...why won't Joomla see the XML file that is in the zip package?

Also, when I try to install component from directory (bypassing upload/install) I get errors related to inability to create folders and setting permissions to 666...

Anyone out ther have any ideas?????

I have posted this on the Joomla forum but I thought I would try here too, since this might be related to the updates I recently did via YUM.

Thanks!!

I have ruled out directory or file permissions...I have another Joomla site on the same server that I haven't made any changes to and I get the same error. This must be related to...

B. Joomla is having difficulty unzipping the file
C. Joomla is having difficulty parsing the xml

or is this the problem:

Session Directory /var/lib/php/session/ Unwriteable

it is set to root:apache and 770
