 Hello

Looks like the Cron Task is executed under a user who doesn't have permissions to open /home/msitepublic_html/periodic folder. Try to check folder's permissions first.

I think the other errors are related to some library which was not installed or installed incorrectly. I recommend you to contact with your hosting provider and ask them about the issue. 

I have 755 permission

this is a migration to a new server, it does not reach that program was installed?
