Had a client add a new book to their AmazonSimpleAdmin collection, and the entire collection list disappeared in the admin section, with a fatal error showing in the AsaCore.php file (at line 654 I believe)- sorry I didn’t copy the error message.
Looking at the AsaCore.php coding, it was a line to do with the URI of the book.
When I found this post I assumed it was an ‘ apostrophe issue. I deleted the book from the database, then the collection reappeared. Turned out several books in the collection have an apostrophe, so clearly we were running a version of AmazonSimpleAdmin which had fixed the issue here.
So I looked up the book on Amazon, and it turns out it has ( ) in the title… so I suspect that’s what caused the breakage.
Not many books have that in their title, so I just told my client to avoid ones like that for the moment – any ideas on how this or other potential symbol problems can be avoided in future. Not enough of a PHP coder to know what to do here…
