The error message is telling you to go and check the file permissions of your site. You can read about them here:

Several months ago wordpress stopped renewing plugins automatically
By default, WordPress has never updated plugins automatically and there are no plans to do so in the future as far as I am aware. Automatic minor core updates were introduced in WordPress 3.7.
Have you checked the permissions on these files? Are they 644?
Thanks.
Sorry, I did not express myself correctly about “automatically”. I meant that wp shows that I have plugins and I need to update them, so before I could go and press the button “update”, put password, ect. And after I could see that there are no more updates.
But now I do that (all the same like before), but wp keeping saying that I need to update the plugin.
So I needed to do it manually, using FileZila, and it is very uncomfortable!
About file permission: The hole folder “includes” has 777, and everything inside also.
I´ve change permission of update-core.php to 644. It did not help. Shows the same phrase when Im trying to update.
Are there other thing I need to change to 644?
Manually delete wp-admin and wp-includes and install a clean version of WP. There may be something stupid sticking around. Keep in mind, your data is SAFE 🙂
Should I put wp-admin and ap-includes of new version of wp or of the one I have?
The one you have, for now.
Well, i tried with one I have and with new version and nothing changed. The same phrase and problem appears.
Any more ideas? What else can I do?
