I recently updated my blog to wordpress 2.5

While I was working on it, I took a look at various plugings available, and I thought I’d try WP Calais Archive Tagger and WP Calais Auto Tagger.

As soon as I tried to activate them, they immediately gave errors:

Parse error: syntax error, unexpected xxxxxxx

where xxxxxxx indicates lots of technical info 🙂

I figured I’d send Dan Grossman an email, asking for advice.

To his credit, he quickly replied, indicating it was a problem with running PHP5 code in a PHP4 environment, and suggested changing .htaccess, or a setting in the website control panel.

Since my cpanel, had no such setting, I did a bit of research, and found that I needed to add 1 line to the .htaccess file in the blog folder:

AddHandler application/x-httpd-php5 .php

Since I discovered that PHP5 can be very different from PHP4, I also double checked all the existing plugins, and the blog in general.

in the end, everything worked well, with no compatibility problems anywhere.
