Hi kymation, husband of Toni here!
We tried again with a tottally fresh installation.
We deleted the database, deleted all OScommerce files and did a tottally fresh installation.
I installed the Modular Front Page addon - this seemed to work fine
I then installed the Accordion Box menu and exactly the same thing happened (clicked 'edit' and the server crashes!).
I know you probably have nothing that you can suggest, but I just wanted to let you know that this is happening for us on a totally clean installation of OSC.
We really want a nice looging categories meu, are there any other addon's from another developer that are similar? Its a real shame it looks like we cannot use yours as it looks fantastic.
Thanks for any help
