You tried to fix it and you get remarks like, there is no attribute "displayText" or Attribute displaytext not allowed on element span?
I have tried searching all over various forums and help sites for solution.
I couldn't understand what they are saying. It is all muddled with technical jargon like element style, span and attribute.
I know they are using the correct and proper terms. But for people like me who are technical-challenged, it is useless to me.
Anyway, I managed to get solved this invalid markup problem.
1. Go to WordPress Dashboard.
2. Click Appearance.
3. Click on Editor.
4. Select Main Index Template (index.php)
5. Look for this code:
<span class='st_sharethis_large' displayText='ShareThis'></span>
<span class='st_facebook_large' displayText='Facebook'></span>
<span class='st_twitter_large' displayText='Tweet'></span>
<span class='st_linkedin_large' displayText='LinkedIn'></span>
<span class='st_pinterest_large' displayText='Pinterest'></span>
<span class='st_email_large' displayText='Email'></span>
6. Change it to this:<span class='st_facebook_large' displayText='Facebook'></span>
<span class='st_twitter_large' displayText='Tweet'></span>
<span class='st_linkedin_large' displayText='LinkedIn'></span>
<span class='st_pinterest_large' displayText='Pinterest'></span>
<span class='st_email_large' displayText='Email'></span>
<span class='st_sharethis_large'></span>
<span class='st_facebook_large'></span>
<span class='st_twitter_large'></span>
<span class='st_linkedin_large'></span>
<span class='st_pinterest_large'></span>
<span class='st_email_large'></span>
7. Click Update File button.<span class='st_facebook_large'></span>
<span class='st_twitter_large'></span>
<span class='st_linkedin_large'></span>
<span class='st_pinterest_large'></span>
<span class='st_email_large'></span>
