When entering a new article submission into the OJS (under step 3 ('Enter Metadata')), the system crashes when a blank line is included (using the enter key).

If the enter key is used to insert a blank line between paragraphs or just to insert a blank line at the end of the abstract, when the author clicks 'save and continue' instead of moving on to step 4, the author is directed to the following (nonexistent) URL: http://environmentalhumanities.org/submissions/eh/author/saveSubmit/3

If the same abstract is entered without any blank lines the system works fine and the author moves on to the following URL: http://environmentalhumanities.org/submissions/index.php/eh/author/submit/4?articleId=4

Any help greatly appreciated.
