Displaying Date in Feed, Open Links in New Window

I was hoping the most recent update would fix the issue, but it seems it is still broken. When I enable the date to be displayed in my feed, I receive an error on the page. Warning: date() expects parameter 2 to be long, string given in /(directory path goes here)/functions.php on line ### I’ve created a test page here: http://www.therealmonline.org/my-thoughts/ On that page, I used the following shortcode: [jp-rss-feed opennewwindow=false url=http://www.therealmonline.org/category/my-thoughts/feed/ dateshow=true dateposition="after" dateformat="l, F j, Y"] Also, if you’ll notice, in addition to the date issue, the links continue to open in a new window despite me attempting to turn that option off both in the settings area of the plugin and in the shortcode. https://wordpress.org/plugins/jps-get-rss-feed/ Found a fix to my date issue here: https://wordpress.org/support/topic/if-date-output-error?replies=3 Still having issues with the opening in a new window thing… 🙁
