Currently I am checking if my site is ok on w3.org

Yet there is tons of problems some are from the modules them selfs

Yet alot is you need to have specified SHORTTAG YES and OMITTAG NO

I have tried seraching on the net to add these, yet I can't find the code.

Can I add them to my XOOPS theme and will it mess up xoops?

Also how do you add them, as I can't seem to find out how?

It shouldn't effect XOOPS at all. What you need to do is add a closing tag('/') to a few things.

change <br> to <br />

change <img src="<{$xoops_url}>/your_image.gif">

to

<img src="<{$xoops_url}>/your_image.gif" />


change <input type='submit' class='formButton' name='submit' id='submit' value='Search'>

to

<input type='submit' class='formButton' name='submit' id='submit' value='Search' />

So you are just adding / at the end of the statement. Those are closing tags.

Hope that helps

Oh I didn't know if SHORTAG YES and OMITTAG NO, was something you could add to the header of a html file, so it switch things off or on??
