Um, in case I’m not the last netfirms user to realize this: the reason why the WordPress version hasn’t been upgraded from 2.0 is that we’re supposed to do the upgrading ourselves.
According to netfirms’ support, new WordPress blogs are currently created at version 2.6, but the user needs to handle the upgrading of existing blogs.
The good news is that this is a quick and painless process. I just followed the instructions in the WordPress codex to upgrade from 2.0 to 2.7, and I didn’t run into any snags. You can do the entire process with nothing more than an FTP program — no command line stuff required. As suggested by the Codex, I disabled all of the plug-ins first, and I manually edited the wp-config file to copy and paste my 2.0 settings into the 2.7 config file.
Wow, WordPress 2.7 certainly has a lot of nice features worth upgrading for. And, as an added unexpected bonus, the upgrade fixed the problem I recently began having when posting to the blog from Zoho Writer. Sweet!
