hover message on product image

I have a woocommerce page selling gift items. A while ago I used a fiverr advertiser to do some work on the website for me and one of the things he did was to mut a pop up message when you hover over the product image on the front page saying “add to basket”. I find this annoying and suspect my customers will too. BUT I cannot find how to remove it.
The developer seems to have disappeared so I cannot get him to do it for me.
Can anyone give me a clue how to find and remove this message.
Easy to see by going to the front page and moving the cursor over any product image.
Tnanks in anticipation.
