(Please) error when clicking "install open journal system" - how to fix?

How to fix this error ??? I click on “install open journal system”, and it continues on the same page and this error appears.

Realizing that the page was all white. I do not know why the user I created in the databases had lost the privileges and I could not fix them. I completely deleted mysql and installed again, but when trying to create new user or connect with root, I did not give permission. Then I installed phpmyadmin, and finally the installation page appeared in the browser. However, this error appears.


I have little to do.
I’ve had enough progress with your help on other topics. Thank you very much in advance.
