I usually use the Google Toolbar spell checking feature to correct spelling errors in my articles. However, I learnt that the if you do not stop the spell checker and publish the post, the highlighted errors can be published. Here is what I got.
The post stayed published with these red and green errors highlighted while I was wondering it was some cache issue on my computer that it persisted. However, when I saw the source code today, the html revealed lot of code had changed making these colored links.
The green color shows a spelling I corrected, while red shows spelling errors (or correct words not yet added to the dictionary). So it is a good idea to stop the spell checker and then publish.
How did I remove the code? By using the “Remove formatting” button in WordPress. Just in case you did not find it, enable some hidden buttons in wordpress!
