I have 5 blogs. All need a version update! Will it cause problems, delete posts, screw up my theme? I don't want to screw them up. I have never updated them from the version I started with so I don't know what will happen! IMJim
after reading this http://scobleizer.com/2009/09/05/i-dont-feel-safe-with-wordpress-hackers-broke-in-and-took-things/ at the weekend you'll find any theme issues are small fry compared to the security issues. Mostly it depends on how long you've left it since you installed. You should always upgrade promptly.
I would export the db files (Tools/Export) and download the template as well with ftp just to be sure, in case you need to re-install it.
Even though i dont need to do it this way, i still prefer to update mine the old way, by downloading the latest copy and making sure i delete the config file from the download and being selective when uploading to the content folder and making sure i have a backup first before doing any of that. I strongly advise upgrading wordpress everytime theres a new one available and not waiting too long.
yep, always backup. There's a cool plugin available now that emails me a backup routinely now too. I like that! I do it manually too, and I don't override the files either, I move the old ones out and the new ones in. The outage is brief but it's worth the disruption to know that it's done right.
