When I try to open a link to my college's library website the message, "disallowed key characters" appears. What does this mean? In the past, I was able to open this link and access the library's catalogs without a problem.

If you use a bookmark to open a specific page on the server then try to navigate to that page starting with the main page or the sign in page of the website in case this bookmark is currently broken.

Supporting the previous suggestion, I saw a library website mention clearing cookies as a remedy for that error message: http://answers.library.utoronto.ca/a.php?qid=979793
