Thank you for a quick reply. I've uploaded a fresh installation using binary transfer mode in Filezilla and created a new accounts.php which I've also uploaded using binary transfer. Still can't login. In addition I'm also now receiving a warning (in Chrome) saying "Resource interpreted as Document but transferred with MIME type application/octet-stream." Enabling debug mode in config.json, the following messages appear in the console:
{Debug::timerStart(): "07. Oct 2020, 14:46:36"}
dashboard:85 {const.php: Server Software: "Apache"}
dashboard:86 {const.php: "Pretty URLs are enabled."}
dashboard:87 {Request::page(): Getting request from QUERY_STRING /dashboard: Array(1)}
dashboard:88 {Request::page(): $GET: Array(0)}
dashboard:89 {Request::page(): $REQUEST: Array(0)}
dashboard:90 {Request::page(): Requested page: "/dashboard"}
dashboard:91 {Shared->__construct(): {…}}
dashboard:92 {Debug::timerStop(): Time for execution: "0.0028760433197021 seconds"}
dashboard:93 {Debug::memory(): Memory used: "2M of 536870912"}
dashboard:94 {Debug::uc(): Automad constants: {…}}
dashboard:95 {Debug::consoleLog(): Server: {…}}
dashboard:96 {Debug::consoleLog(): Last error: null}
Are they indicative of an issue you recognize?
