Link between Author & Book not working with SEF enabled

[Madeleine]

Hi,
Everything is working fine except that when I enable Joomla's standard SEF settings from the Global Configuration panel and then go to an author and try to click on a book I get a 500 error (if I just have the first setting ticked) and a 404 (if I have both settings ticked), even though I can visit the book normally via the book catalogue.  I'm using Jooomla 3.4.8 and 3.1.0 for the library.  I've left the development site up and enabled SEF settings so that you can see the problem at http://mcmullinmarketing.com/authorway/.  Can you help please?

Madeleine, try to install the latest version (Abook 3.1.1) then tell me if the error occurs yet.

Hi Federica
I've tried that and am still having the same problem as before: a 404 if both are on and a 500 if only one.  I can supply log in details if you want to take a look?

Are there the category menu and authors menu?
If not, create them and retry.

[Madeleine]

Yes there are menu items for both category and authors.  I have 3 different categories on the top menu but that shouldn't make a difference should it?

Can you tell me your url website?

It is  http://mcmullinmarketing.com/authorway/
Many thanks for your help
