Hi there is a typing error on the submit button of the blog. It should be "submit" and reads "Sumbit" How do I fix this? Thanks

Hello,

Go to comment.php present in your theme directory and follow the instruction as shown in image given below

 

Thank you. That worked. When we change other documents besides the CSS do we need to set up a child folder or can we just make the change directly like this. Do we have to worry we we update the theme. thanks

 

Hello,

We will update the solution above in our next theme update.So there is no need to create child theme for that.
