If you’re installing Thesis for the first time… (via official installation instructions)
- Upload the new Thesis 1.6 folder to your
/wp-content/themesfolder. - Locate the
/custom-samplefolder and change its name to/custom. - Locate the
layout.cssfile inside your newly-renamed/customfolder, and change its permissions to 666. - [optional but highly recommended] If you’d like to give Thesis the ability to auto-crop thumbnail images for you, then you’ll want to change the permissions of your
/custom/cachefolder to 775. - Inside your WordPress dashboard, go to Appearance ? Themes, and then activate Thesis 1.6.
- You’re done, but make sure you check out both the Thesis Options and Design Options pages that now exist inside your WordPress Dashboard. You’ll be able to do things like set up your navigation menu, set fonts and font sizes, select your layout, and much, much more. To put it simply, this is the part of Thesis you don’t want to miss!
If you’re upgrading Thesis…
In version 1.6, the /custom folder contains more files than it did in previous versions. Follow the directions below very carefully to ensure that you have a seamless upgrade!
Your new /custom folder should contain the following files and folders:
/custom[folder]custom.css[file]custom_functions.php[file]layout.css[file]/cache[folder]/images[folder]/rotator[folder]
The only critical change here is the addition of the /rotator folder. In the future, instead of copying both your /custom folder and your /rotator folder, you’ll only have to move your /custom folder, and that’ll take care of every possible customization you can make to Thesis.
In order to provide you with the best possible navigation solution, I had to make significant changes to the nav menu CSS classes for version 1.6. If you’ve customized your nav menu extensively, then these new changes will no doubt affect your existing styles. If you need assistance in adjusting your styles to this newer, better structure, please drop us a line in the forums.
- Back up the
/customfolder from your existing Thesis installation to your hard drive. Also, if you’ve uploaded your own images to the/rotatorfolder, then you’ll want to back that up, too. After you’ve done that, you should move the/rotatorfolder into the/customfolder on your hard drive. - Upload the new Thesis 1.6 folder to your
/wp-content/themesfolder. - Rename the
/custom-samplefolder to/custom, and do not overwrite this folder with your existing/customfolder! - Instead of overwriting the new
/customfolder with the one you just backed up (as you are probably accustomed to doing with previous versions), copy the contents of the/customfolder you backed up in Step 1, and paste it all into your new/customfolder, which should also containlayout.css. - Set the permissions of your new
layout.cssfile to 666. - Make sure your
/cachefolder’s permissions are set to 775. - Inside your WordPress dashboard, go to Appearance ? Themes, and then activate Thesis 1.6.
- Visit the Design Options page, ensure that Thesis is not giving you a warning about the file permissions on your
layout.cssfile, and then hit the Big Ass Save Button.
