Hi Mohammad,
Sorry for the late response.
I tried to use real time find and replace as you said, but could not be fixed.
Can you see if I enter something wrong below?
Find:
<span class=”wishlist-out-of-stock”>’ . __( ‘Out of Stock’, ‘swiftframework’ ) . ‘</span>’
Replace with:
<span class=”wishlist-out-of-stock”>’ . __( ‘SOLD OUT’, ‘swiftframework’ ) . ‘</span>’
Please advise!
