upgrade to php 7.4

Hi Stif, I hope you are well. I am writing to you just to ask you a question: on an important page for me, I have BackStop Elegance 2.8.6 installed because with 2.8.7 some image galleries with carrousel stopped working. Until I can switch to another Theme, do you know if Elegance 2.8.6 is compatible with php 7.4? Thank you so much for your kindness and help over the years. All the best,

James
