I saw your posts here.
What error?
I decided to install the plugin in my development environment see what issue you could have and this worked for me.
I have the job listings and I have the button working.
You need to go into the settings of RSJP resumes (only area for settings) and set a page for Resume Form Page and a page for Display Jobs Page.
Did you do this?
Then take the shortcode [resumeForm] and place it in the Resume page.
Then take the shortcode [jobPostings] and place it in the Job Postings page.
Then when you create a job posting at the end of the page place [rsjpSubmit] and the button will show and when people click it they are shown the submit form.
As for attachments, I did not test this – but based on what I could see, this is how you set it up at a base level and then grow it from there. I see a lot of potential in this.
Let me know (I am not the author, just a person who saw your post.. and figured I’d help by testing the plugin)
