getting this error after upgrading to php 7.1:

PHP Warning: A non-numeric value encountered in /public_html/wp-content/plugins/new-royalslider/classes/rsgenerator/NewRoyalSliderGenerator.php on line 339

I'm using an older version of the plugin here (3.2.4), wondering if this is fixed in the latest version or if there's a manual fix?

Thank you

    Make sure that there is a number in thumbnail width & height inputs (in "Thumbnails,tabs,bullets" section of slider options).

    I’ve got two galleries with no navigation and about 30 with thumbnail navigation. All of them have these settings (screenshot attached).

    Just double-checked and there’s not a single one with blank thumbnail size, so that doesn’t seem to causing the error.

    Please try to update, automatically, or manually as described on top of the changelog

    If the issue persists - let me know.
