I followed this tutorial to achieve the effect.
When I scroll to the bottom of the page, where it should load "Next Page" contents, it ignores the isotope.js and loads "new content" underneath previous content.
There is a step in the tutorial I did not follow because I am not sure what the "textdomain" is. I understand that could be the problem so if you could enlighten me on what my "textdomain" is, I will appreciate it very much.
If you need any more information to help me figure this problem out, let me know. I appreciate any and all help.
