OJS error: Cannot use a scalar value as an array

[martinv]

Hi,

A user has been setting up a journal on our multi-journal OJS v. 2.3.8.0 site. With display_errors and show_stacktrace on, he encountered the following errors in a number of places, eg. on the Journal's "About" page (http://journals.domain/index.php/jnl-abbr/about):

ojs2 has produced an error Message: WARNING: Cannot use a scalar value as an array In file: C:\Inetpub\wwwroot\path-to\ojs\classes\journal\JournalSettingsDAO.inc.php At line: 80 Stacktrace: Server info: OS: WINNT PHP Version: 5.2.6 Apache Version: N/A DB Driver: mysql DB server version: 4.1.12a-nt-max-log

So far, the error has not prevented the user from completing an action and turning stacktrace and error display off hides the messages, but I am concerned that severe problems (such as those mentioned in viewtopic.php?f=8&t=9379 "Article editorial process page broken for all roles") may occur once the journal becomes actively used.

I have not found any null values in the journal_settings table. Locale is either an empty string or 'en_US'.

This journal was created after upgrading from OJS 2.3.6. Only this one journal's about pages show the error, other journals created previously under earlier versions do not.

I would appreciate assistance with solving this error. Please let me know if any additional information is required. System info and the full stack trace follow below the signature.

Regards,
Martin
