[Koha] OPACSuggestionAutoFill - must be set to 1 or 0

[Fairlamb, Christina]

Hello all,

Koha 22.05

I've been adjusting settings for purchase suggestions and tested out the
Google Books API, after adjusting this setting in System preferences I now
get a warning on the system information page:

Warning : System preference 'OPACSuggestionAutoFill' must be '0' or '1',
but is 'yes'.

when set to enable or:

Warning : System preference 'OPACSuggestionAutoFill' must be '0' or '1',
but is 'no'.

when set to disable.

No message was there before adjusting this preference.

Kind regards

Christina
