Hopefully, this will be the first of many contributions I can make. I came across an opportunity to submit a fix for the Elementor widgets add-on by Theme Isle. I’m using this plug-in on the Herding Pixels site. I was having trouble with setting up a hyperlink with a price-table element. Upon reviewing the PHP code for the add-on, I saw that there was a bad variable reference. The code is well-written, so it was easy for PHP noob like me to trace the problem back to the source. I fixed the bad references in my code, tested it, and then made a codex forum post. ThemeIsle responded quickly and has already released a patch.
