You have a problem on your server, I had it cpanel presents a bug to my step, check the extensions in your hosting in php, in the php selector you appear, verify that the mysql extension is enabled, change to higher php if you use 5.3 select 5.6 or higher, verify that the minimal extensions are enabled and try again, in my case it was the database that broke the connection to the store, I had to mount a clean installation, connect a new database to configure the Php and then import the old database so that everything is normal, then upload the images
