I have already moved two older blogs to the new platform, old WP installs with no auto-update function. The first one went fine and even my own super hacked and ugly theme still works and is exactly as ugly after the upgrade as before.

The second upgrade was also on an old 2.2.2 install but this time I had to face some challenges. Install went find but upgrading the plugins gave this error:

Warning: touch() [function.touch]: SAFE MODE Restriction in
effect. The script whose uid is  is not allowed to access /tmp
owned by uid 0 in /path_to_wordpress/wp-admin/includes/file.php
on line 198
 
Download failed. Could not create temporary file.

With no plugins upgraded… now what?

Easy: The _khAttAm_ blog already solved the problem for me, I just skipped the owner part, made a chmod 777 /tmp folder inside the wp folder, updated wp-config.php according to the instructions and that’s it.

Ok now with plugins updated I noticed that some of the plugins had both an old version, that was activated, and a new version that was inactive. I had to manually delete the old versions for 3 plugins and activate the new one… strange.

Next issue (how many are there) is that the old default wordpress theme throws an error with WordPress 3.0.  In single post view, the post is followed by this error:

Fatal error: Call to undefined function the_terms2posts() in /home/sbyholm/domains/milesgallon.com/public_html/blog/wp-content/themes/default/single.php on line 19

I think it might be a plugin for related posts that doesn’t support 3.0… maybe… I’ll use the new Twenty Ten Theme instead… but that one does not support all the plugins I have installed… bad….

Anyway Twenty Ten has a clean and nice look and I’ll stick with that, have to check for new plugins that support 3.0

Now I’ll just have to check that the Woo Themes support 3.0 before updating this blog, I’ll make a new post on the other side.
