after php 7.3 upgrade Health Check & Troubleshooting info page not displaying

hi,

i just upgraded to Debian 10 and upgraded all the relevant php7.3 and apche2 packages. (running wordpress 5.2.2)
after upgrade every thing is working, only problem i face is with Health Check & Troubleshooting plugin and especially its “info” page.
when i click the page i display partial code.
—————————————————————————
add_help_tab( array( ‘id’ => ‘converter’, ‘title’ => __( ‘Categories and Tags Converter’ ), ‘content’ => ‘

‘ . __( ‘Categories have hierarchy, meaning that you can nest sub-categories. Tags do not have hierarchy and cannot be nested. Sometimes people start out using one on their posts, then later realize that the other would work better for their content.’ ) . ‘
‘ . ‘

‘ . __( ‘The Categories and Tags Converter link on this screen will take you to the Import screen, where that Converter is one of the plugins you can install. Once that plugin is installed, the Activate Plugin & Run Importer link will take you to a screen where you can choose to convert tags into categories or vice versa.’ ) . ‘
‘, ) ); get_current_screen()->set_help_sidebar( ‘

‘ . __( ‘For more information:’ ) . ‘
‘ . ‘

‘ . __( ‘Documentation on Tools’ ) . ‘
‘ . ‘

‘ . __( ‘Support’ ) . ‘
‘ ); } require_once( ABSPATH . ‘wp-admin/admin-header.php’ ); ?>
cap->manage_terms ) || current_user_can( $tags->cap->manage_terms ) ) : ?>

Categories and Tags Converter available from the Import screen.’ ), ‘import.php’ ); ?>
