Hi, there is a issue open for a few month regarding DNS Zone imports: https://git.ispconfig.org/ispconfig/ispconfig3/-/issues/6345 I want to get this working, to make my life easier. As correctly statet by Dovi Cowan this issue occures because checkDomainModuleDomains gets called with the domain_name instead of the domain_id which it expects. Code: $app->tools_sites->checkDomainModuleDomain($soa['name']) Code: checkDomainModuleDomain($domain_id) Could we just fix this by getting the domain_id from $soa['name'] and hand the id over to checkDomainModuleDomains? I'm not that familiar with ISPConfigs code, is there an internal function to get the domain_id by domain_name or should we query the db for the id? any thoughts and input is appreciated!
