crontab error with installation

Question

I have a problem to install cron task on debian server. It was working on my mint station, but when I implement it to crontab and try to install it, it is not working. Can you help me please? User mikrotik is added to group crontab and files are executable.I also tried to run it via at, no change, here is the output.

Answer 1

The problem is probably due to the editor you used, some editors add newlines in some places. crontab reads the first column and will report an error if it is not an integer or #.
