I'm brand new to web development and I've installed Joomla on my website. For whatever reason I can hardly do anything because my PHP version is only 5.3 according to Joomla.
However, using my cpanel I changed the PHP to 5.5.
How do I get Joomla to update the PHP version?
Additional info: This is what it looks like, I don't understand why Joomla has a different php version.Below is also the error message I see when I try to install a template package.
