Thanks for waiting our response,really appreciate it.
1) Actually we need to check it, I think it’s caused by plugins. Could you give us access to your dashboard?.
2) You can add additional style to remove dates from posts. Navigate to Curated Options > Additional Settings > Custom CSS and paste this code
3) It need to custom module core in php file. FYI if you update it, will replace to default.
4) Unfortunately it’s no possible in Curated Theme
Hope this helps,
