default site settings permission in sharepoint

[Charles-André Bélanger]

Hello,
We did some changes in the security on our site settings, but I would like to revert back, can someone list me the default security as it is at the creation?
thanks

Mine look like this:

[#2]

What site it is .. (the site template)?

[#3]

this is what I have on my team site,  just change the teams site member to "Edit" that is the only difference I see 

[#4]

thanks, I thought "everyone except external user" was listed as "read"

this is under my site settings permission level

[#5]

I think you have enabled some SharePoint features that add some additional security groups such as the publishing feature. If I recall well, disable that feature will not rever back your security configuration

Yes Juan, you are correct it wont remove the security role entries even after we remove the SP features.
