Why get 404  error all of a sudden?

My Linux Apache website has been working fine for a very long time.

All of a sudden, earlier today I keep getting 404 file not found error messages for images, .pdf files, css and any non-.html o or non-php file.  This is so strange.

The only think I changed today was my email address in Plesk. Nothing else.

Any idea what would cause this type of issue.

A file that was accessible fine a few hours ago all of a sudden is giving a 404 warning error?

Everything else works

    The obvious question - do the files still exist?
    Are you sure nothing else has changed?  Maybe PHP has been upgraded?
    Is this shared hosting?

    Anything in error log related to errors?

    Maybe you installed some f apache rate limiting modules recently, then with mail addresss change users download all pages again instead of checking etags and you hit ratelimiter now and then.

    Building on what @Gary asked: perhaps folder permissions have changed?  The files may indeed exist, but if your web server can't access the directory, they might as well be gone.

    The first think that I would be looking at is the apache error_log file.    Most obvious would be either missing files, folders, or the permission to those files/folders itself.

    I do not have much experience with Plesk.  So I am not sure if changing email address could trigger the 404 error.

    It was a technical issue on the server side. They initiated an update that failed and they had to roll back a change.

    All good suggestions, but ultimately it was something different.
