My D7 creates anchor tags automatically when 'www.*****' in text is found.
Example:
<span class="class">www.site.com</span>
produces
<span class="class"><a href="www.site.com">www.site.com</a></span>
but
<span class="class">site.com</span>
produces
<span class="class">site.com</span>
Corresponding field value stored in DB still has <span>www.site.com</span>
. Could not any signs of such an action in theme scripts. In known modules neither. Had anyone met something like this? Maybe some guess where to look for?
