Tutorial: Fixing WordPress 2.7 XML-RPC Issue

[smartads]

I have tried a couple desktop blogging clients with my newly installed WordPress 2.7. Unfortunately, all of them have problems when I tried to publish the post to my blog. At first, I thought it’s the compatibility problem between the blogging clients and WordPress 2.7. Finally, Daniel Jalkut from Red Sweater Software points me out it is a bug in WordPress, libxml2, and PHP (it seems they don’t work well with each other and the problem has existed since 2008).

I tried to update libxml2 and PHP to a version that can fix the problem, but it seems not very easy with my account in the hosting company (one of the reasons I should hosting my own machine in the data center instead). After a quick research, I found the other solution to fix this problem: Patch WordPress 2.7. Jon Canady posts a fix of this problem by patching a file in the WordPress. After I applied the fix, everything works again like magic!!!
