I resolved the problem (with the help of my friend Morpheus).
First I set up PHP 5.6 in the CPanel of my hosting.
Next I enabled the fileinfo extension in my PHP Selector.
Now I can upload images without problem in my installation OJS 3.0.2.
Thanks for this wonderful forum. I have learned a lot from the dark with you.
However, I can not upload images or css in my system. I’m under Php 7.1, and with OJS 3.0.2. I only have the message: No file uploaded or invalid file type!
Many of the suggestions on this thread have to do with the way OJS detects uploaded files’ MIME types. Have you investigated those suggestions? If so, please describe what you’ve tried and what the result was.

Thank you very mucha @asmecher!! I resolved it, was a problem with a path dir_files…
But now i have a problem with the navigation…
The navigation bar does not load well, and I think it causes it not to load everything well. As you can see in the image, the footer covers the section of my uploads of authorship.
Sorry for my english, and thank you very much for all the support you give (besides the great software you have done).
