Hey @cra_admin,
This sounds like a problem caused by either your theme or a plugin. Did you install or update anything recently, before you noticed it?
Have you done any initial troubleshooting yet? If not, please rule out a theme issue or a plugin conflict. I recommend testing things on a staging site rather than on your production (live) site. Many hosts provide a staging service, where you can do testing without affecting the live site. You can ask your host about this. If they don’t give you a staging site, you could try WP Staging or Duplicator:
https://ww.wp.xz.cn/plugins/wp-staging/
https://ww.wp.xz.cn/plugins/duplicator/
First, temporarily switch to Twenty Seventeen, which is one of the default WordPress themes. You can do this by installing a plugin that only switches the theme for the current user, linked below:
https://ww.wp.xz.cn/plugins/theme-switcha/
See if the menu reappears when you switch. If it does, you’ll need to contact your theme’s developer to see if they can help you troubleshoot.
If things still don’t work properly with Twenty Seventeen, please try checking for conflicting plugins.
To do so, temporarily disable all plugins but WP Job Manager (and related addons), and see if the issue resolves. If it does, try activating your plugins one-by-one and try to reproduce the problem. If the menus disappear when you activate a particular plugin, you’ve found the culprit.
Just a side-note; before you deactivate your plugins, we recommend that you make a full backup of your site.
Let us know what you find!
we’d really ideally like to have users submit their job postings directly there
Your instincts are good, here — we definitely recommend that all jobs are added via the frontend form on your site, since several verification steps are not taken when adding a job via the Job Listings > Add New path in wp-admin.
Cheers.
