So this entry isn’t about Perl but it is about a distant cousin, PHP, and the WordPress blogging software (v2.1+) spell checking bug that results in the notorious message:
Could not execute AJAX call, server didn’t return valid a XML
First let me start by saying that WordPress is a tremendous piece of software. I only have good things to say about it. Now that that is out of the way…
In WordPress v2.1+ there is a WYSIWYG option for writing posts, pagesÂ and comments. It isn’t full featured, but it is easy to use and provides the basics. It even includes a spell checker (which I am using as I write this). It is this spell checker that is causing so many people problems. When many people try to use the spell checker they receive the error message cited above. WordPress.org has a thread on this: http://wordpress.org/support/topic/101689
Having run into the same problem I decided to spend a couple of hours tracking down the problem and I can say that I have fixed it (on my system at least). My platform is running Windows Server 2003 with IIS and WordPress v2.2. I have patched my system and spell checker is working like a champ.
