Permission Denied Message on Terminal Startup – MacOS, Bash, Terminal

Everytime I start my Terminal I get this error message:

-bash: /Users/myusername/.profile: Permission denied

I still can use the Terminal as usual though.

It probably came after I installed something that is using the terminal.
It seems that something is trying to access .profile which doesn't exist.
Note that .bash_profile exist.

I ran the command:

grep -n profile ~/.* 2>/dev/null

And got this result:

I also added set -x at the end of the /etc/profile file and got this result:

To me, it looks like the application MAMP is causing the problem, am I right?
