Below are the upgrade instructions which are just the generic instructions normally provided for Dolphin. I am open to suggestions on any rewrites to these instructions to make them clearer if needed.
Cheetah Upgrade Instructions from 1.1.0 to 1.2.0
Back up your current Cheetah files, folders and database.
NOTE: This upgrade will work with the official Cheetah 1.1.0 version ONLY. If you applied some fixes to your Cheetah 1.1.0 then this patch should work in most cases, but there are some fixes that may cause conflict.
Download and extract the patch Cheetah-Patch-1.1.0-1.2.0 and upload its files to your current installation, replacing all old files. Make sure that old files were REALLY replaced - the site can become nonfunctional at all if old files are still in place.
Remove the upgrade/.htaccess file via FTP or SSH.
Make sure that you removed .htaccess file from "upgrade" directory! Do not remove .htaccess file from Cheetah root folder, it will make almost all links on the site stop working.
NOTE: You may need to change your FTP client settings to show hidden files to see the .htaccess file in your FTP manager.
Open the following URL in your favorite browser:
Replace your-domain.com and path-to-cheetah with your real values.
Apply all available updates. The script detects suitable updates automatically.
Please follow and read all automatically completed steps of the upgrade script, paying special attention to the last step. The last step of this upgrade is IMPORTANT. You will be given special instructions by the script which you will have to do MANUALLY.
