The default “Leave a Reply” title can only be changed in WordPress’ source code. Headway Themes does not provide an easy option to make this change so you will need to make this change directly on a wordpress file. In this tutorial, you will need to search for the wordpress file, edit using notepad and re-upload the file.
Some people like to change this to a different word like “comments” or “discussion” but be careful when making changes on your source files – keep a backup copy of the original files and always remember where these files are located so you can reverse the process.
Step 1: Get the file
Using an FTP, download the file from your wordpress’ wp-includes folder.
Location of File
Step 2: Search the word “Leave a Reply”
Using a notepad, search for the word “Leave a Reply” and you will find at least 4 of them. I noticed that changing the word “Leave a Reply” below “function comment_form_title” reflects in Headway Theme (line 1198 if your notepad displays numbers). Simply change the existing word to what you want it to be and make sure to put it inside the existing single quote.
Step 3: Save the file and reupload
Save the text file and re-upload in the same location you took it from. Take note that this modification can revert back to original when you update your wordpress to a newer version. What important is that you know how to change it the next time around. Studying a little PHP for fun doesn’t hurt either.
