Hello how are you, what happens is that I updated the PHP version from 7.4 to 8.0. I use the Finance Template, but first I tried it on another server and everything worked but when I did it on my server. When loading the site I got an error. I attach the image. and for it to be fixed I have to unzip the backup of the installation files that I had previously. How can you solve it.

I have the files and the database from the previous backup before making the updates but I don't know if restoring it scares me that it won't work. Can you help me.!
