After upgrade, can’t read comments

Are you using the stock template or have you edited it in any way?

You probably didn’t update the comment line as the upgrade docs said.

I’ve triple-checked, and I made all the changes required by Podz’ upgrade instructions. When I switch to the default theme, comments appear. When I switch back to my original theme (which, as best I can tell, I modified correctly according to the Podz instructions), comments disappear.

For clarification, I modified the wp-comments.php and index.php files from WP 1.2.

Would I screw everything up if I replaced my theme’s comments.php file with the comments.php file from the 1.5 default theme?

Only the modifications you may have made to it.

Do you have your blog running in a subdirectory? We had this problem and I had to go into Options>General and change WordPress address and Blog address to be the same (Before, the WP address was https://slumberland.org/wp/ and the Blog address was https://slumberland.org/). When this was done, the comments reappeared.

I am having exactly the same problem. Only now I can comment and then I get the error:
Fatal error: Call to undefined function: checkaicode() in /home/blahblah/public_html/wordpress/wp-comments-post.php on line 40

So I know that I’ve got to change some code somewhere, but I’m not sure where or what it is! This is taking days!

if you have an index.htm in your root directory, delete it.

checkaicode() is a function from AuthImage plugin. you may have disabled that plugin but the code is still there. remove these lines from wp-comments-post.php, if they are there and your authimage plugin is disabled:

// AuthImage
if ( !checkAICode($comment_code) )
die( __(‘Error: please enter the valid authorization code.’) );
