Thread:Extension talk:TextExtracts/PHp Warnings in version 1.24

Getting the following error message: 'PHP message: PHP Warning: constant: Couldn't find constant ApiBase::PARAM_HELP_MSG in /opt/bitnami/apps/mediawiki/htdocs/extensions/TextExtracts/ApiQueryExtracts.php on line 349\nPHP message: PHP Warning:  constant: Couldn't find constant ApiBase::PARAM_HELP_MSG in /opt/bitnami/apps/mediawiki/htdocs/extensions/PageImages/ApiQueryPageImages

Any help in what's causing would be great. Thanks
