The isn’t really that bad as far as I can see – I’ve seen infinitely worse, and this is not a crisis really. Sure you have validation errors, but nothing that can be fixed. Frr whatever reason, you have frames, which you need find in your code and remove unless it’s part of the theme.
https://validator.w3.org/check?verbose=1&uri=http%3A//www.cydco.com/nd/ndblognew/
Things like <center>
require a closed tag to be valid. The theme itself seems to be ok, but you’ve made some changes that are causing the page to be invalid – you’ve got a few open divs that need closing, and floating unordered list tag.
With regards to comments, the first two errors mean that you have the content defined twice – you have them set as id, so you cannot use that same css call twice. Unless you define it as a class. id’s are for individual elements that will be used only once, class is for elements that will use the same call more than once in a page. Get rid of the second call.
43: <div id="content">
44: <!-- end header -->
45: <div id="content" class="widecolumn">
Is your code – so note you have content starting in your header and in your index.php. Remove line 43 and replace it with line 45.
These are very minor errors that can be resolved with a bit of work.
I’ve not seen a WP theme that uses tables in calenders and has validated. I could be wrong, but that always seems to through up in the validation.
For the frames side of things, this is your code:
<HTML>
<HEAD>
<TITLE>ninjadoll.net</TITLE>
</HEAD>
<FRAMESET ROWS="100%,*" FRAMEBORDER=0 BORDER=0 FRAMESPACING=0>
<FRAME NAME="content" SRC="https://www.cydco.com/nd/ndblognew" marginheight=0 marginwidth=0 noresize scrolling=auto>
<NOFRAMES>
<META http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<META http-equiv="refresh" content="0; url=https://www.cydco.com/nd/ndblognew">
</NOFRAMES>
</FRAMESET>
</HTML>
Remove this. I’d go in more detail but I have to go.
Good luck
