We moved our WordPress site from one cPanel account to another whilst changing domains. Everything in CiviCRM seemed to be working OK. But we've just hit a problem.
I can go to Reports -> Contact Reports -> Contact List - and get the screen with columns, filters, sorting OK.
But when I try to Refresh Results, or Print etc I get a 404 Not Found error.
Any help or hints of where to look would be much appreciated.
