Several hours ago, my friend Rogger from Brazil sent me an e-mail asking about the Jobifier theme. This theme is a job board WordPress theme.
When someone that registered as a job seeker applying for a job, the job owner will not receiving his/her application. Only the administrator who will get this including the job seeker as the copy.
To fix this bug, you can easily download the patch here and upload it via FTP to directory: wp-content → themes → jobifier → includes → form and replace the existing file.
