Alias of resources are converted to lowercase after savecheck the TransAlias plugin settings
I disabled the "ManagerManager" plugin, but I still cannot make a resource "unpublished".
it’s probably the default ManagerManager rules chunk that sets the pub_date automatically when the ressource is created. you’d need to uncomment that rule and delete the pub_date field.
Clearing the published date field did the trick. You were also right about the TransAlias settings; Trans table was set to utf8lowercase.
sorry, i meant the Publish date field
