We need a source for the name "Sclerdermonasterium", which doesn't look likely to be correct. German makes compounds like this -- Latin hardly ever does. There probably is a Latin name: we need to confirm it and cite the source. If there is no source, the page will have to be moved.
The link to "British History" doesn't work (click it and see). It may be simply that an extra | has been added at the end of it, but, removing this, we just get to the British History main page. That's not what we need. We want a link to the page that has the information about this abbey. Go to that page, copy the whole of the address as shown in your browser (CTRL + C) and paste it into the footnote (CTRL + V).
The links have been completed by repeating the web address, like this: <ref>[http://www.british-history.ac.uk| www.british-history.ac.uk]</ref>. This is just a waste of everybody's time -- please don't do it this way any more. Please complete the links not by repeating the address, but (a) by pasting in a title, in the original language, from that web page, or (b) by saying in Latin what information the link has to offer.
