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 I'm 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? 
I see files in Filezilla, but the internet denies their existance

Firstly, can you upload a unique file to the root dir and then check on the internet that it is there. Just wondering if you have for some reason connected to the wrong area/account. Have done this myself before.Also, can you clear the whole directory and then upload one of the non-working files and test?Or create a sub directory and upload to that, testing one file at a time.Give us a list of the file names & directories, and a url we can test?Also as Paulmorriss says, check the file name case as non windows servers are a bit fussy about this. You have F5'd/refreshed Filezilla to double check the directory does contain these files
