 * And then i need to click back to go back to wp.
    Can anyone please help?
 * Also i have noticed on the new version that when an image is uploaded and sent
   to editor i can not use the alignment function. Every time i do and then save
   i lose the image. Or even when i upload images and send to editor it does not
   send but gives the error code.
 * When i write a page and use home as my slug the title still appears under the
   pages category. It never used to do that. The home page title would not appear
   under the pages category. I have a static front page installed and never had 
   these problems with the previous version.
 * Please someone help.
 * cheers
    Steve

 * If you use a unompatible up to WP 2.3, you will get these errors. For example;
   [
   Table ‘wordpress.wp_categories’ doesn’t exist] error means, wp_categories table
   doesn’t exist and WP 2.3 doesn’t have this table. Before wp 2.3, WordPress haved
   this table but now, not. For the other errors, maybe, you didn’t install WP correctly.(
   Sorry, my English is very poor.)

 * It is this simple: do NOT use themes and/or plugins that are not compatible with
   WP 2.3.1.
    Deactivate all your plugins and try a compatible theme – does it work?
 * Also, there is a sticky post on the front page of this forum addressing your 
   error. (btw, it is NOT a bug, it is a human error, as in the 99% of the cases)

 * Thank you. It was uncompatible plugins.
