I upgraded at least seventeen (17) sites and blogs that I maintain using WordPress as a blog publishing platform as well as WordPress as CMS. I upgraded straight to WordPress 3.4.1 version as I was not able to upgrade to WordPress 3.4 “Green” immediately.
I did not have problems with the sixteen (16) sites and blogs hosted with Dreamhost and two (2) other hosts in Switzerland. Everything went fine but I had a problem with the site hosted at Yahoo! Webhosting. The first time I attempted to upgrade the site, it failed because of bad gateway.
So I waited for two (2) days before upgrading it. I did not do anything but waited. The next time I upgraded the site, I did not have any problem at all.
I do not know exactly what happened when I got the message “bad gateway” the first time I upgraded the site but at least not proceeding to upgrade it when I got the “bad gateway” was not a bad idea.
I still have three (3) more sites to be upgraded. I did not upgrade them because of a certain problem, a recurring problem actually. The problem was the same with the problem that I mentioned when I upgraded to WordPress 3.0 “Thelonious”.
Actually, before I upgrade the sites and blogs, I normally upgrade them locally. I installed locally all the sites and blogs in my local computer where no one can see them except me which is ideal for testing. If there are any problems that would occur I would know exactly which sites and blogs should not be upgraded.
If you would like to know more about WordPress 3.4 “Green”, watch the video clip below.
WordPress 3.4.1 is a maintenance and security release which addresses several bugs found in WordPress 3.4 version.
Before you upgrade though or every time you upgrade, make sure to backup your database and files. Make it a habit please, backup your database and files.
