[Plugin: Quick Post Widget] Plugin won't post, issue with sessions

I’d really like to get this plugin to work, as it would do exactly what I need. Help/advice appreciated!

When activated, I am able to use the widget in a page and when I load the page, everything looks great. However, when I go to submit a post, the page reloads- text disappears from the boxes, no post is submitted, and no success message appears.

I later noticed that the http://www.mysite.com/wp-login.php page displays these errors at the bottom:

Warning: Unknown: open(/home/content/04/3364807/html/sessions/sess_lddj0l64o6c8pfquqi4kt0png3, O_RDWR) failed: No such file or directory (2) in Unknown on line 0

Warning: Unknown: Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/home/content/04/3364807/html/sessions) in Unknown on line 0

I’ve been doing research and finding discussions of similar errors with other plugins such as: http://wordpress.org/support/topic/plugin-wp-e-commerce-errors-immediatley-after-activating-plugin

I have been trying to follow along with the fixes- created a /tmp folder in my root, modified the permissions, added:

session_save_path(‘/home/content/xx/xxxxxxx/html/tmp’);

(xx/xxxxxxx being my account number) to the wp-config.php file, as well as quick-post-widget.php and CaptchaSecurityImages.php.

Tried creating/uploading a php5.ini file to the root with:

session.save_path = “/home/content/##/#######/html/tmp”
upload_tmp_dir=/tmp

Error still persists! I’ve skimmed the forum and didn’t see anything pop out with solutions for this error and this specific plugin.

other misc information: hosted on goDaddy (client signed up for hosting before I did the research on the many issues goDaddy has with WordPress), recently switched from windows server to Linux to fix slow-loading problems and various time-out errors with site.

Any and all advice would be very much appreciated!

Thanks 🙂
