Upgrading Drupal

I have attempted to use taxonomy weights to order the display of nodes on a page under 4.4rc. I am using a mixture of the new flexinode module and stories, and also have multiple terms defined per node. My expectation of behavior has been that if 3 terms are defined per node, and two of the three taxonomy verbs are identical, the weighting of the third will order the display of the nodes on the page. Unfortunately, this does not appear to be occuring.

Since upgrading to 4.4, I've been getting the following email:

Out of the blue, my 4.4rc site stopped displaying content. THis occurred after my attempt to upgrade to the latest image and node_image modules, but unchecking those modules doesn't seem to roll me back to functionality.

I'm getting the following error under 4.4rc when I try to access project forums:

Fatal error: Call to undefined function: table() in /home/pflug/public_html/praecedo/modules/project/project.module on line 73

Any access of individual projects I've created also seems to fail. Any ideas?

i am getting the following error even though i can still input new vocabulary and have it take effect. the whole format of the page does get a little wonky (appropriate technical vocab comes in handy)- i've checked and my user name is correct and so is my database name -
i did not have this problem until after i upgraded. what do i do?

user error: Access denied for user: '*******_eva@localhost' to database 'selfeste_drupal'
query: LOCK TABLES sequences WRITE in /home/********/public_html/drupal/includes/database.mysql.inc on line 97.

I upgraded my site from 4.3 to 4.4 today (fixed a few issues i was having) but now when i try to go to admin/configure/themes i get this error message:
Fatal error: Class theme_marvin: Cannot inherit from undefined class basetheme in /home/jmw/trappedinhell.com/html/themes/marvin/marvin.theme on line 4

anyone know how to fix this or to bypass it to change the theme?
