The client set the task, but gave access only to those files that are not used by the engine. As a result, the work was done, but on the unused files and the person began to complain that the work was not done( the pages were not optimized). After all the explanations, the customer refused to provide access to the admin and the current files of the site, argumenting this by the fact that there everything is encrypted. In general, I asked for access to the admin and bd, and finished work by changing the code through the admin. I will not cooperate with him anymore. Except for support and advice on the work of my code.
