 * I set up WebLibrarian on an offline test site a while ago and all worked fine.
   
   Installed on the live system and have a problem with checking out. All appears
   to function correctly until you click on the ‘checkout item’ button. The screen
   goes blank and nothing else happens. When I refresh the page I get the ‘Circulation
   Desk’ page back but the book has not been checked out.
 * When I went back to my offline version it wanted to upgrade WordPress. After 
   it had done this I was getting the same behaviour on that version too. I can’t
   remember what the previous version was but both are now running 4.9.8 with WebLibrarian
   downloaded/updated 2 days ago.
 * So both systems, on Chrome and Firefox are showing the same issue.

 * Ahhh. Version updating seems to be a red herring. The real bulk imported list
   had blank circulation types and I generated these later in circulation types,
   but each item still had a blank unless edited individually only then did it assumed
   the first one by default. This caused the unfriendly blank page, an error message
   would have been nicer.
 * So how to edit or remove a circulation type name? The only option appears to 
   be changing the duration. I now have a set of unusable types as I misapprehended
   their use.

 * You will have to directly hack the database or else delete everything and reload
   correctly. The type field is important for checkout and hold: it contains the
   loan and hold period. The *typical* use is to limit DVDs to a 1 week loan period
   as opposed to books having a 3 week loan period, since one can watch a movie 
   in one evening, but reading a book (eg “War and Peace”) will take alot longer.
 * I thought that it should have generated an error when uploading with bad type
   field values. Something I need to look into sometime.

 * When you say ‘delete everything’ do you mean the whole collection, or remove 
   the plug in or something in between? I tried deleting the collection but the 
   circulation types remained.

 * I meant clearing out the collection. To clear out the types you will need to 
   directly access the MySQL database. You will need to have a set of types defined
   before reloading the collection, and the collection needs to have the proper 
   types referenced in order for the hold and checkout periods to work properly.
   The types provide the loan period, for example “book” might have a 3 week (21
   day) loan period and “dvd” might have a 1 week (7 day) loan period.

 * OK thanks for clarifying.
    Actually I have found that if a bulk imported list
   contains a type not previously defined, that type is automatically created when
   an item of that type is first checked out, which is kind of useful.
