hi pw, there is 3 place you need to check.
1. jobplanet dashboard > required page & url > required page
2. jobplanet dashboard > required page & url > URL Endpoint
3. pages > all pages > check all permalink url
if 1 of those page using same permalink / url name. it will automatically failed.
previously i also having the same problem. but the problem is always the same, double same URL that causing issues.
