There was an inconsistency in the data received from your browser. This may be due to one of several things:
Sometimes, if you used your browser's "back" button during an operation like a submission, clicking on a button may try and do something that's already been done, such as commit the submission to the archive. Clicking your browsers "reload" or "refresh" button may have similar results.
If you got here by following a link or bookmark provided by someone else, the link may be incorrect or you mistyped the link. Please check the link and try again.
If you have more than one browser window open with DSpace, this can cause a similar problem whereby a button clicked in one window may make a button click in the other window invalid.
Of course, you may have uncovered a problem with the system! All of these errors are logged, and we'll be checking them regularly to see if there is a problem.
If the problem persists, please contact the site administrators:
