You're telling it to do the same thing 3 times, which is always to replace " is" with " was".  The first replace is straightforward.  The second replace uses parentheses to specify that the space is a subgroup (which isn't necessary for this example), and the replacement is the word "was" preceded by the same pattern that "is" matched on.  Since it can only match on a space, the replacement will be " was".  The third replacement is doing the same thing, but it also creates a second subgroup out of the entire thing, and once again the replacement matces with " was".What do you expect to happen?

Make sure you have the right path.  Print out the variable __FILE__ to see the current path and filename.  Sometimes hosts don't let you see the actual path when they set up a virtual directory, but you can't use the virtual directory path to open a file.

make sure the file and folders have hte needed permissions.
