Thanks Ernest, that would be great if you could roll out a fix!
I can say for sure that in my scenario, multiple uses of a variable will not function. (result container header – info box text):
<a href="?post_type=product&s={phrase}">View all product results</a> (link functions correctly for this button)
<a href="?s={phrase}">View all blog results</a> (link for this button will not work as phrase already used)I have not tested multiple uses of the same variable in the ‘redirect to url’ or on ‘show more url’ settings but I would guess the same happens
