PROBLEM Error 404 after changing some text

[Tania]

did you change the slug ?

I did and now the page gets a 404 error. Other/data/pages.xml shows the correct slug. I don't remember what I originally had in there.

When I try to load the page, the error message says it cannot find index.php. This is not the file that should be loading. The URL in the address bar points to the correct page.

Short of deleting the entire data folder and uploading it again, is there something else I can do?
