Fix a job email alert for website

Hello Developers,

I need a talented developer who is able to help me fix the Job Alert function of my WordPress job-board website and bring it up to working code.
The work will involve –
• Investigating the website and ensure you understand the code.
• Review how the job alert has been set up, and fix the errors. (The Job Alert Feature has been developed but it is not picking up all the jobs under the various categories etc. Also, once one job alert has been sent, it stops working and tells users that there are no jobs under the parameters selected for the Job Alert – even though there are plenty of roles available).
And then style the email to include job title, salary, location and expiration date.

Another important aspect of this job is that the developer must be able to check and test their work and ensure each part is done with no errors.
I am happy to share site with shortlisted candidates.
Please let me know.
Victor
