Codeigniter HMVC Cron Job (CLI) Failing - php

Question

I am using HMVC with codeigntier and try to run a cron job.
I am using this for the cron:
php /home/onlblcm/dev.mytranslator.com/index.php mytranslator cron cronTranslations > aaa.txt 2>&1
When running this from cron job, in aaa.txt file I get
Set-Cookie: ci_session=e56ef3d7d05652937b3269852d8b36eaeebba9a2; expires=Wed, 05-Sep-2018 13:39:26 GMT; Max-Age=7200; path=/; HttpOnly

Cache-Control: no-store, no-cache, must-revalidate
Pragma: no-cache
Refresh:0;url=http/http/user/login
Content-type: text/html; charset=UTF-8
So it's super strange for me.
If I run the exact same command
php /home/onlblcm/dev.mytranslator.com/index.php mytranslator cron cronTranslations > aaa.txt 2>&1
From Putty (ssh) I get what I need. The file runs good. I get the desired output.
So it's the exact same command, but with CRON it fails.
I checked to see in SSH, and I am using user onlblcm
I checked the cron, and it's using the same user: onlblcm
So what can be the problem?
EDIT1:
I added -f in front of the index.php and I now get the error output:
A PHP Error was encountered
Severity: Warning
Message: ini_set(): Headers already sent. You cannot change the session module's ini settings at this time

As you can see, it's going to: /home/onlblcm/dev.mytranslator.com/application/modules/admin/controllers/Admin.php
But that has no sense, since I am not calling my admin controller.
Again, if I call the command from SSH it's working, from CRON is messed up.
EDIT 2:
I added to cron jobs this command:
php -f /home/onlblcm/dev.blasteronline.com/index.php > az.txt 2>&1
I get the exact same thing (error) when calling from Cron Job.
If I call it from SSH I get no output.
if I call from cron, I get the error like above.
EDIT 3:
I now managed to get the same error when using Putty/sssh.
If I run the command (ssh) with
php ....
It runs good
If I run the command (ssh) with:
/usr/bin/php
I get the same error like in cron.
With cron I tested with php ... and /usr/bin/php ... and I get the same error.
So somehow php is different than /usr/bin/php .
But I outputed the phpinfo and it's the same version.
When I use php info (via ssh) and use php I get a 32KB file with information (not html formated). When I use /usr/bin/php calling a file with php info, I get a file with 94K info (it is html formatted).
What is happening? Any ideas?
EDIT 3: SOLVED
It seems somehow the cron was calling a different PHP (although same version).
From Putty (ssh) I did a "whereis php"
I found 2 folder: /usr/bin/php AND /usr/local/bin/php
It seems calling simple php or /usr/bin/php FAILED the cron
When calling the cron with /usr/local/bin/php IT WORKS
Thanks
