Hi @Shahadat, thanks for taking the time to report this!
However, you are using a version which is too old and not supported anymore. Developers are no longer working on that version, so unfortunately there will not be any bug fixes by developers for the version that you use.
By upgrading to a newer version of MediaWiki you will receive bug fixes, security updates, and new functionality.
If the problem still occurs with a newer and supported version of MediaWiki, please set the status of this Phabricator task back to "Open" via the Add Action... → Change Status dropdown, provide exact version information, and follow https://www.mediawiki.org/wiki/How_to_report_a_bug . Thanks!
