Hi! How to update these components?
Use JA Extension Manager to update the JoomlArt templates and extensions.

Take a backup of site first as you are using older version of template and there are many new versions released after that with new code changes and fix.
Thank you! Great, updated! But with mistake, look at the attachment. Is it ok?
This appear PHP warning during update, its no longer showing now http://prntscr.com/z1mnly
