This one has me puzzled. I've installed the Prism plugin on both my live and test installation. In the test version, code is coloured correctly, on the live version, it is picking up values from Vastitude's style.css, but I've been unable to identify why. On the face of it, both are set up in the same way.
Both use the same version of b2evolution - v6.4.4
Both use the same skin - Vastitude 1.1
Both have had their CSS modified to change the header image, default font size to 1.1em, and line spacing to 1.4em, nothing more
Both have the Prism plugin enabled and set the same way - Opt-out & Never
Both have had a post created using the same JS content - the live version is here http://izdihar.com/index.php/prism-plugin-test
And looking at the browser dev tools, both have loaded the prism.css
The difference is that the test version is using the Prism CSS, where the live one isn't, I've not been able to work out why though.
Any suggestions where to look next?
