Strange letter while upgrading OJS from to 3.1.0

We have upgraded OJS from to 3.1.0. We have the following issues and questions.

Please see the following link:

  1. We have seen a strange letter (aÂ) in many places like in references and copyright terms. How can we edit this letter as we can not seen the reference section in the metadata? (In the older version we saw the references in the metadata).

  2. Please let us know the the location of copyright terms. We are unable to edit the copyright terms.

  3. There is no PKP PN plugin. We have downloaded ojs-3.1.0., No plugin inside the downloaded source code.

  4. We would like to know whether our journal is under LOCKSS program or not.

Thank You

Please check your locale settings in Please post it here. I Noticed that you have issues related to locale settings. Which database and PHP you use?

I am using PHP 5.6.30 and mysql database (database server version 5.5.51-38.2).

Please find the file:

; Localization Settings ;


; Default locale
locale = en_US

; Client output/input character set
client_charset = utf-8

; Database connection character set
; Must be set to “Off” if not supported by the database server
; If enabled, must be the same character set as “client_charset”
; (although the actual name may differ slightly depending on the server)
connection_charset = utf8

; Database storage character set
; Must be set to “Off” if not supported by the database server
database_charset = utf8

; Enable character normalization to utf-8 (recommended)
; If disabled, strings will be passed through in their native encoding
; Note that client_charset and database collation must be set
; to “utf-8” for this to work, as characters are stored in utf-8
charset_normalization = Off

Thank You
