Keeping Custom Templates Update Safe
ASA1 (legacy)
This page documents ASA1, the predecessor of ASA2. ASA1 only receives security fixes and Amazon API updates. Looking for the current plugin? See the ASA2 documentation.
By default, ASA 1 looks for the HTML template files in its subdirectories /tpl/ and /tpl/built-in/.
You should never change the file in built-in as those are the templates shipped with ASA. They will be overwritten with new updates. You should put your custom templates one level higher in the /tpl/ directory. On update, ASA 1 tries to copy all files in the /tpl/ directory to a temporary destination and move them back after the update process is completed. However, this might not work on every server.
The best place to keep your custom template file is a subdirectory in your theme (or child theme) directory called “asa”. This folder is the first ASA checks for custom templates and it is absolutely update safe.Remember: No matter where you keep your custom templates, it is always a good choice to have a backup.
