My Template

[davetest]

Upgrading template from v1.0.3 to v1.0.4 is it possible to copy over the old cfg.php and update from that in plugin UI or is it best to start withthe new cfg and re-enter old data manually? Thanks.

Make a copy of the old cfg.php.

The new version adds new variables for the new component. 

As well as new variables in the translation files.
// v.1.0.4
$my_template_admin_sidebar
Need to copy it to old translation files.

Then copy the new cfg.php
Open the plugin settings and save them.

The first time they save, PHP-notice can be. Because there are no new variables in the old cfg.php. After saving, they will appear.

I copied over old cfg.php and old content appears in both frontend and in plugin fields, but save button doesn't work. Maybe I broke old cfg, but copying that back to old template on another test site works there. I'll test further.
