Getting a "Fatal error: Uncaught exception 'Zend_Cache_Exception'"

I am trying to install Omeka on a server running a Parallels Plesk Panel setup, which I've never used before. When I navigate to the URL for the location where Omeka is installed (studentview.gatech.edu/project), I get an error. Navigating to the install directory (studentview.gatech.edu/project/install) throws the following error:

Warning: realpath() [function.realpath]: SAFE MODE Restriction in effect. The script whose uid is 10024 is not allowed to access /tmp owned by uid 0 in /var/www/vhosts/studentview.gatech.edu/httpdocs/project/application/libraries/Zend/Cache/Backend.php on line 185

Can someone help me figure out what is going wrong here? Thank you in advance!

Sorry, re-reading what I posted, I should clarify. I haven't actually been able to run the install yet. I've only completed the steps preliminary to the actual install.

This error is being caused by PHP's "safe mode" restrictions, which stop PHP from being able to open or write many files on the system.

The most straightforward way around this is to get your host to turn off safe mode, if they're willing.

Just had the same error when i tried to install omeka on a apache-server( shared host), but with "safe mode off" (PHP 5.3.13)
Is there anthing, i can do?

Same problem for me.. Safe mode has been disabled as well. This is the error that is showing up for me:

Is it possible that open_basedir is on?

The Zend code being used here tries to automatically find a temporary directory it can read and write to. Usually a server has at least one such place set up, since PHP needs at least a temporary directory to handle uploads.

Hi John, Thanks for your reply,

My apologies - I don't know where to find open_basedir is that something I should contact my host about?

also - I have installed Omeka in a subdomain, and there is a wordpress installation in the main public_html folder, so there is a tmp folder there, that I believe is for the wordpress site. Could this be causing an issue?
Thanks so much for your help

phpinfo() says:

open_basedir

local value:
/www/htdocs/w00f62d0/:/tmp:/usr/bin:/www/htdocs/w00f62d0:/bin:/usr/local/bin:/usr/share/php

Master value:
no value

And btw. - I also have a WP-installation in the root and OMEKA in a subfolder

Thanks for Your help

Hello,
I was able to find phpinfo()

open_basedir no value no value

I've just attempted to install Omeka 2.3, without success, and appear to have encountered the same (or similar) problem as 'Erin Paved Arts' (see earlier posting). Just wondering how this was resolved?

I receive the following error message at stage-6 of the installation instructions: "Open your web browser and visit the URL where you uploaded the omeka directory".

Fatal error: Uncaught exception 'Zend_Cache_Exception' with message 'Could not determine temp directory, please specify a cache_dir manually' in /mysite/omeka/application/libraries/Zend/Cache.php:209 Stack trace: #0 /mysite/omeka/application/libraries/Zend/Cache/Backend.php(217): Zend_Cache::throwException('Could not deter...') #1 /mysite/omeka/application/libraries/Zend/Cache/Backend/File.php(130): Zend_Cache_Backend->getTmpDir() #2 /mysite/omeka/application/libraries/Zend/Cache.php(153): Zend_Cache_Backend_File->__construct(Array) #3 /mysite/omeka/application/libraries/Zend/Cache.php(94): Zend_Cache::_makeBackend('File', Array, false, false) #4 /mysite/omeka/application/libraries/Zend/Cache/Manager.php(173): Zend_Cache::factory('Core', 'File', Array, Array, false, false, false) #5 /mysite/omeka/application/libraries/Zend/Application/Resource/Locale.php(106): Zend_Cache_Manager->getCache('locale') #6 /mysite/om in /mysite/omeka/application/libraries/Zend/Cache.php on line 209

Attempting to access phpinfo() within my omeka directory produces the same error message as above; yet accessing it at the same level as the omeka directory works, and shows open_basedir with no value, no value.
