Ecwid will be rolling out some changes to their base themes over the next few weeks.
These changes will be used on all new shops, and be an option to apply on existing shops.
All current e-shop designer themes are now compatible with both the old and new style Ecwid themes.
If you enable the new themes in your Ecwid control panel, you may need to update your e-shop designer theme to the latest version to avoid problems with the look of buttons on your store.
To update a theme (or a tweak) go to your "Manager" page and click on the "update" link for the theme you are using.
An "update" link will only show for any theme or tweak that is out of date.
Note. updating a theme may take a minute or two in some cases, please be patient.
