Fix XHTML errors
 

I have like 53 from my site, how do you fix all these error?

Thanks https://vborg.vbsupport.ru/

They are all template based errors. If you look at the w3schools validation (http://validator.w3.org/) it tells you the code that is not XHTML vaild, so just go into the templates, find the code, and learn XHTML to make it correct (if you don't already know it thoroughly). A hint: Don't forget to add " />" after tags that normally have nothing in between (Such as image tags, line breaks, horizontal tags, etc...) For example, <img src="test.gif"></img>, would become <img src="test.gif" /> - Notice the </img> tag is taken away and replaced with a " />" (don't forget the space.)

what are the errors?
URL to site?

its www.talkfitness.org :)

Wow I have: Failed validation, 225 Errors :(

Wow, that's pretty sad. I passed with no errors :D

Even vbulletin.com has one error :o

Why are people so obsessed with W3C Validation errors?

Because it makes you look more professional :)
