The plugin is compatible with Avada, one thing to try please, in the template field (on Total price tab), you have two fields for singular & plural labels, fill anything there (even if not used in the final template) and see if that fixes it please.
If not, reach us please at [email protected] and we will be glad to take care of this.
I took your advice and it worked! Thank you! However, if the single product page has a strikethrough discount, then it is not displayed. This is relevant for the “instead” mode, in my case. Can you do something about it?
