Working on a new install (haven't installed CA certified SSL yet), I can browse to http://example...admin...event search ( search participants) or 'advanced search', or 'manage events', or seemingly any other menu items but going to 'search contacts' the url generated has ' search' It is a WP frontend and the baseUrl doesn't specify httpS:// yet.
Three things to try, in this order:
- Administer menu » System Settings » Resource URLs. Ensure "Force Secure URLs" is set to "No".
- Clear cache and templates_c.
- Rebuild the menu:
