Doesnt work on site. Needs module or extension?

On The Snow Changed the name of their rss files
Change line 496 (I think) to:
$url .= ‘/snow-rss.html’;

What does that mean?

You have to edit the plugin file and change that line so the plugin grabs the right file from onthesnow.com rather than getting an error message.

I wasnt getting an error message it just would be a blank page

I was referring to the plugin getting an error message from the website which caused it to display nothing.

There is a error message from the plugin, hidden as a comment in the html code.

Falcon13 is right. I had the same issue on https://kingstonmass.com/ma-ski-reports/. Here’s the fix: Copy all the code in snow-report.php to an editor and search for the string snow.rss .

Change both instances of snow.rss to snow-rss.html , recopy and paste it back to the edit plugin window, save changes and it will work as advertised. You can also use the replace function, using “find what” snow.rss and “replace with” snow-rss.html to do the same. Thanks to Falcon for helping with the correct answer!
