Block absolutely will not update
The changes will not update on the site. All caching is off, the cache has been cleared manually several times, and the browser cache is cleared.
When I use dev tools on the page, it is not outputting a new div that I added to the view.php file, and furthermore I deleted the entire view.php file from the directory to induce an error and it still displayed the old page list. So I'm pretty confident it's a caching problem - any ideas?
It's possible you updated your site through the dashboard and the actual core that's being used is in the /updates directory, not /concrete.
This solved it, thanks!
