I’m sure that by this time most of you must have found out that WordPress 2.7 (Coltrane) has been released and it’s because almost every blog on WordPress niche have blogged about it already. And of course, the WordPress panel alerts you as soon as there is an update available. However, with every release there is one issue that pops up inevitably and that is the incompatibility of certain plugins or themes.
What’s the cause of that ?
As WordPress is evolving and being actively developed, there are few changes made to the core or how queries are sent to the database and various other things. This can break those plugins or themes that depend on the certain features which may have been changed for the new version.
Although, most of the plugin authors ensure that they update their plugins to keep it working with the new version, however I’ll still suggest to test everything to be on a safer side.
What can be done to find out that if this version will work with my current set of plugins and themes?
Testing is the simple answer for the same. I know it sounds time consuming and complicated, however this will ensure that your blog will continue to work properly, even if you upgrade to WordPress 2.7. Here are few simple things which you can try -
1. Install the WordPress through cPanel/Fantastico or any other installer, if provided by your webhost. You don’t have much choice if your webhost is not so kind on their customers, you can do a manual installation (that hardly takes time). Make sure that you install it on any test location (in a sub-folder or by creating sub-domain – I try it using sub-folders).
2. Most likely, it’ll be the older version that you can upgrade in around 2 mins. with the help of WPAU or you can surely take the manual way and in case you are going the manual way, feel free to skip backup of database (you are going to do the upgrade on fresh installation, so need to do the backup of database or files).
3. Put the themes and plugins in respective folders and then activate all of them, Make some dummy posts that will ensure that you’ll have a dummy installation of WordPress.
4. Check if every aspect of your blog is working fine or not? Don’t forget to check every single section, be it category pages, archive pages, single pages, try to make comments etc.
Once you are done with the checking and you become sure that everything is working fine, then you should do the upgrade on your main blog. However, make sure that you make the backup of files and database before you do the upgrade.
