I just upgraded from 3.0 to 3.1.2 and in the comments column under Posts in the WP Admin, this error keeps appearing for every row:

Warning: number_format() expects parameter 1 to be double, string given in /path/mysite/wp-includes/functions.php on line 155

Can someone tell me how to fix this?

  • What Plugins do you have installed? – Chip Bennett May 10 '11 at 18:04
  • Advanced Excerpt, Akismet, Category pagination fix, Disqus Comment System, Feed JSON, WordPress Importer, and Yet Another RElated Posts plugin – Zoolander May 10 '11 at 18:08
  • What normally displays in that column? That is not a default Column (EDIT: actually, yes it is). I suspect the warning is coming from Disqus? – Chip Bennett May 10 '11 at 18:46

The "Comments" column is not a default/core column in the "Posts" page. Perhaps it is being generated by your Disqus Plugin?

Try temporarily disabling the Disqus Plugin, and see if the PHP notices go away.

EDIT: actually, it is a default column. But I still suspect Disqus is causing the PHP warning.

  • This error has been reported here for the Disqus plugin. So if Zoolander can confirm it is Disqus, this question becomes a duplicate. – Jan Fabry May 10 '11 at 19:15
  • Yes, when I deactivated the Disqus plug-in, the warning went away. Unfortunately, it needs to remain activated, so now it's just a matter of fixing the plug-in. :( – Zoolander May 10 '11 at 19:24
