In addition to generating a database of words on all the pages of our Web site, the college's search engine also checks for some common mistakes in HTML syntax and sends automatic email messages to the owner of the file containing the error. The search engine searches for files using a method which is similar to that used by outside search engines like Alta Vista and Web Crawler. You should examine other files for a link to the file containing the error and remove the link until the page is fixed. The files listed in an error report may also have been discovered, not because of an HTML error or broken link, but by your having a directory without an index file such as index.html , index.htm , index.shtml or index.shm . In such a directory, a Web browser will present a list of every file in the directory.
File contains invalid characters.
This seems to be a file, not a directory. There is no file or folder with this name Check to make sure the file listed is actually located in the place described by the path. Another mistake is using spaces in a filename, which is not permitted. Some browsers don't mind this, but others do. This error can usually be detected by the WebLint script.
