We cant upload files in submission after upgrade from 3.2.1.1 to 3.3.0.6. I have right dir for files, rights are set to 777 for files dir. It shows error message “Slim application error” or “Invalid JSON response from server.” after chosing file. When i reach http://ojs.umb.sk/index.php/bu/api/v1/ it says {“error”:“api.404.endpointNotFound”,“errorMessage”:“Po\u017eadovan\u00e9 URL nebylo rozpozn\u00e1no.”}
Please help.
Thanks!
Tomas
