Not totally sure 3.5 is the correct version nor do I know how to make that determination correctly. That said the site was originally on Windows server through GoDaddy.com and the load time was slow to non existent. I was advised to switch to Linux, which I did and it loads fine now but the site lost the CAPTCHA function and I am clueless as to how to fix that.
Also I need advice on where to find a tutorial for WordPress to help me learn how to make changes, add metatags, etc. for this web site which is http://www.pbs-av.com.
