If you check the source code of http://techkumar.com, you will see that the <Div> tags are also there. Having the <div> tags before the <!DOCTYPE> tag will definitely not be validated HTML.
Have you tried opening the actual plugin file in a text editor and changing it there? Or you can re-download the plugin and override your current copy. Hope that works!
i have deactivated the plugin, but it still showing me, i have searched for most of the pages like index.php, header.php for those HTML tags but i didnt find them.
The plugin editor itself not showing any HTML tags, i have downloaded the plugin file and opened in Dreamweaver but it didnt had any such tags.
I have deleted the plugin still no it shows errors. Please tell me which file contains those HTML tags. I have tried most of the files.
Which plugin do you think it’s coming from? Can you search for ‘zd_CommentsWidget_widget’ in all your files — themes and plugins and see if anything comes up?
I’m pretty sure you checked this, but can you double check if you are you editing/deleting files on the correct server?
Do you have any other information that we can help you pinpoint the problem with?
How can i perform search on the server? Yes i am editing and deleting on the correct server. I think the HTML tags have added to the core WordPress installed files, what do you say?
When i check my blog home page(http://techkumar.com/) source i am seeing
<div class=”zd_CommentsWidget_widget”>
</div>
these HTML tags at the top. I think since the header file has .php extension it is starting with <php tags, may be i should change the header file from .php to .html , what do you say? Is it safe to change index.php extension?
