I started developing a magento 2 website a dedicated server with an IP lets say (126.96.36.199) with Centos 7 and when I finished my development I downloaded the whole html folder (magento root) with a mysql backup and I reformatted my dedicated server and i putted Centos 7 with Plesk. I followed an article about migrating my website and i uploaded the files restored the database, connect the database with the files, changed the core_config urls and when I hit my domain on browser its says me "File not found.". Some of my plesk error logs can be shown here(1.http://prntscr.com/jdtyyw 2.http://prntscr.com/jdtz8g 3.http://prntscr.com/jdtzkc 4.http://prntscr.com/jdtzox) If anyone knows what happens here please help me unstuck from this, Every help would be appreciated. Thank you!
-----EDIT----- I corrected the file permissions When I run the command line
php bin/magento setup:upgrade
