The specific file had to be added from core component -
\components\com_solidres\layouts\asset\confirmationform.php
to replace the one located in override - /templates/ja_hotel/html/layouts/com_solidres/asset/confirmationform.php
- Have renamed the earlier file to confirmationform_old.php in similar file path
Have also reported this with JA Dev Team ever since JA Hotel had been launched quite prior and integrated extension - solidres extension has been updated with new version releases ever since and latest version release is Solidres 2.8.1 Stable
This would enable concerned team to review and check if certain template override files, if any, require change in wake of having the specific template override compatible with latest version of Solidres
