# errors, errors and more errors

 * [18 years, 3 months ago](https://wordpress.org/support/topic/errors-errors-and-more-errors/)
 * Currently I am using WP 2.23. I have been wanting to upgrade to 2.3, but I keep
   getting DUPLICATE key errors like what was described in [this post](http://wordpress.org/support/topic/139999?replies=10).
 * So I quit and reverted back to 2.23 and began to notice the following error messages:
 * > WordPress database error: [Unknown column ‘option_description’ in ‘field list’]
   > 
   > INSERT INTO wp_options (option_name, option_value, option_description, autoload)
   > VALUES (’category_children’, ‘a:0:{}’, ”, ‘yes’)
 * So I followed the instructions [at this link](http://www.wp-wordpress.com/themes-and-tricks/resolved-wordpress-database-error)
   and was able to resolve that problem.
 * This whole process started because I have been getting a slew of errors from 
   2.23 like the following:
 * > PHP Warning: Cannot modify header information – headers already sent by (output
   > started at /home/blacki5/public_html/wp-includes/wp-db.php:132) in /home/blacki5/
   > public_html/wp-includes/feed-rss2-comments.php on line 2
 * and the following just started yesterday:
 * > PHP Warning: session_start() [[function.session-start](https://wordpress.org/support/topic/errors-errors-and-more-errors/function.session-start?output_format=md)]:
   > Cannot send session cache limiter – headers already sent (output started at/
   > home/blacki5/public_html/wp-content/plugins/enhanced-wp-contactform/wp-contactform.
   > php:233) in /home/blacki5/public_html/wp-content/plugins/enhanced-wp-contactform/
   > wp-contactform.php on line 233
   >  [Sun Feb 24 06:12:36 2008] [error] PHP Warning:

 * I was getting a bunch of fatal errors that were pointing to various plugins that
   were unused, so I deleted them (Currently, the only plugin I have enabled is 
   Spambam). This wiped out many of the error messages, but the ones I listed above
   still exist. I also checked to see if there was any whitespace on line 2 in the
   feed-rss2-comments.php file as indicated in the first error I listed. From what
   I can tell, I did not notice any extra spaces.
 * I listed both problems here because I need help in figuring out if it would be
   easier to fix the upgrade problem or to maintain my existing 2.23 version. I 
   am completely open to both options.
 * Last point, when it comes to understanding PHP and other related programing, 
   I am far from being a pro. Thank you for your help.
    ** Other stuff:
 * I tried to run the export tool in wordpress that would create an xml and that
   just produced a blank page with no file.
