Hi afarahani!
Please go to Dashboard > Updates and “re-install” WordPress and check if that helps. Issues are not theme related.

Hi, I re-installed WordPress and nothing changed. Now what?
Yes Sir! I have done it. No difference.
Hi!
Add this to theme functions.php or wp-config.php:
error_reporting(0);

The issue is fixed, but still I am curios to know why there are so many errors? Do you have any explanation? Is it theme errors?
No, they weren’t theme errors. Probably something in WordPress or one of your plugins.
