Hi to all i resolved this, because this site its on a vps, we had change the php version to php8 but some php packages were not installed for that version the package i needed was mb_detect_encoding this is for giving php the capabilties to process CSV information. i had to enable and installed it on WHM cuz this site use CPANEL and the package on whm is called php80-php-mbstring. also try to use chat gpt to install it if you don’t understand how to do it hope it works for all
