After upgrading a 1.3.5 phpwcms site to 4.12 all worked but the site wasn't w3c html validated anymore. In the html source I found the error, a comment <!-- wasn't closed. See the code below
Code: Select all
<meta http-equiv="content-style-type" content="text/css" />
<style type="text/css">
<!--
<style type="text/css">

-->
</style>
