Pls use the attached main.js file instead of the current one js/main.js file .
(Unzip the attached file and add the file in to appdev/js folder ) . The issue is due a JS error and we are submitting an update today to get the fix to everyone.
Use the same procedure as when you installed the theme for the first time.
Everything you did on your Dashboard won’t get overwriten, the files you’ve modified, however, will be replaced with the new files. I recommend that you save them in separate folders so you’ll have them at hand to reapply the changes.
It makes a backup of the existing plugin/theme as well in the media folder so you can always revert back or refer to the earlier version. If you made any changes to the source files (instead of child theme), you will need to redo them of course no matter what method you use for updating.
