Errors in debug.log

I was debugging an issue unrelated to this plugin, and noticed that I’m getting errors on every page load, all generated by this plugin:

[19-May-2017 01:10:47 UTC] PHP Notice:  Array to string conversion in /var/www/html/wp-content/plugins/bowe-codes/includes/shortcodes.php on line 269

The above error repeats about 22 times, each time I load a page.

I realize @imath is no longer supporting this, but his blog says @dot07 has taken over. Hope someone will hear and lend a hand.

Thanks!
