I am doing some updates to a 10-year old site, and I am baffled. Everything worked great locally, so I uploaded a bunch of stuff to the server using filezilla. Within filezilla I can see all of the files, but for some reason I get a 404 when trying to view them.

It seems as though (at least for the folder Im currently checking) this is happening for items which are "farther down the list" alphabetically. I tried to re-upload a file individually but it didn't change anything.

Is this an indication that I hit some sort of limit with the hosting company? And if so why can I still view the files from filezilla? Please offer guidance. I am at a loss.
