How to upgrade1) First, make a backup of your database.
Log in to your cpanel and find the backup section.
You should see a line saying "Download a MySQL Database Backup" and under that, your databases names. Just click on the one you want to download (in this case your Coppermine database.
2) With either ftp program or cpanels file manager, backup your include/config.inc.php file, your anycontent.php file and your "albums" directoy to your own computer.
(VERY IMPORTANT!!!)3) With Winzip or similar, unzip the archive "cpg1.3.5.zip"
4) With your ftpprogram or cpanels file manager delete the file install.php ifexists in coppermines root directory.
5) Now upload all the files and folders from the unzipped "cpg1.3.5.zip", except for the "albums" directory, include/config.inc.php file, your anycontent.php file.
6) If you have not already done so, create a folder called "edit" within your "albums" directory - this folder will be used by coppermine as a temporary folder, do not ftp-upload files there. Make sure the new "edit"-folder is CHMODed the same way your albums-directory is (755 or 777, depending on your server's config)
7) Now you are almost done. You can now log out from your ftp-account.
With your browser navigate to yourtch-hosted-domain.com/copperminefolder/update.php and follow the instructions.
AdditionalIf you have made a custom theme, see the theme.html inside the doc directory for how to apply eventual changes.
You can not use language files from older versions of Coppermine - make sure to only have the language files that come with this package inside your lang folder (delete or rename all files from older versions within the lang folder)
This was an upgrade guide to the version mentioned in this thread, however, most coppermine upgrades are done the same way.
Have fun with your Coppermine gallery.
