I'm building custom WP theme and I have issues with sliders. None of those I've tried to install worked. When I looked into the developers console, and searched for their js/css files, they where not there. Not in the header or the footer. One of those plugins had option to include his files into header or footer - tried to change that but didn't work. Contact form and pagenavi are working just fine, but sliders not. There are no js errors, because there are no files to cause them. WP version is 3.8.3. jQuery 1.9.3 is included and working fine. Am I missing something in my functions.php ( theme is made from scratch ) maybe?
As Chip notes in the comments: alway use the jquery bundled with WP. When you are developing your own theme, always make sure
wp_footer are present.
Plugins assume you are following these standards and will make sure their sliders or whatever work with them. Using other versions of jquery essentially means the slider scripts becomes untested and may not work.
