How to prove to the client that we did not break the site?

Question

Web development

We are doing a project (online store), the client has access to the site . Recently, a client calls and says that the layout on the main page "broke", the page template was indeed changed, but we are 100% sure that it was not we who changed it. Apparently the client gave access to other people and they already messed up something there. How to prove our innocence?

Answer 1

Use a version control system (i.e. git ). You can always see the changes that were made and not brought into production.
A useful command for your case git diff, which outputs changes to files that have not yet been added to the index. The comparison occurs with the latest commit.

Answer 2

Logs, who came. Or do you all have one log/pass?

Answer 3

Weird. Well, for example, we also do not have dev-prods, gits and other things. But the FTP account is issued separately and you can see when it came in. Another issue is that we do not give access without a written statement waiving the guarantee.

Answer 4

If only by the IP addresses from which they connected
