I’m developing a small Wordpress e-commerce site using the Jigoshop plug-in. Their newest release broke my site, and Jigoshop support told me that:
“Getting your hosting service to upgrade your website’s version of PHP to at least 5.3 is the best fix.
For now though, you can replace this file with the enclosed version of
But be forewarned, the next major release will have even more PHP 5.3 dependant items and getting the website updated is the thing to do.”
I am not actually sure what version of PHP I am currently working with. I am running a small WordPress multisite install on a Dreamhost VPS which I initially set up in August, 2011. How do I determine what version of PHP I am running under? How do I upgrade my site to PHP 5.3 (or better)? I am very much at (or beyond) the limits of my competence here. Any clear and not too technical advice would be greatly appreciated!
