In the settings for the plug in there is the option to change the following (for clarity I've CAPITALIZED THE portion that can be changed)
Button text used to show review form: CLICK HERE TO SUBMIT YOUR REVIEW
This button will be shown above the first review.
Text to be displayed above review form: SUBMIT YOUR REVIEW
This will be shown as a heading immediately above the review form.
Text to use for review form submit button: SUBMIT YOUR REVIEW
I've tried to change the first one to: Share your Review / Comment
(leave the second one blank)
Change the 3rd one to "Submit"
But when I click on "Save Changes" the changes are NOT saved by the plugin.
