Notify site administrator of WP update?

Check you wp-config file for this: define(‘DISALLOW_FILE_MODS’,true); and remove it or change to false.

2. Try creating a new admin user and see if you can update using that account.

I am having the same problem. Adding a new admin does not change the message and I have checked wp-config and there is no define(‘DISALLOW_FILE_MODS’,true);

Any other suggestions very welcome as I now cannot update core or plugins.

Thanks

Same problem. Adding a new admin does not change anything and I have checked wp-config and there is no define(‘DISALLOW_FILE_MODS’,true)

Anyone found a solution?

Thanks

I found the site I was dealing with had been hacked with malicious code inserted in various places including at the beginning of the wp-config file and on virtually every .php file in the site as well as additional htaccess files added. I had to re-install all the WP Admin and Includes files and clean up files on the server and in several plugins.

so no simple solution unfortunately.

Good luck

Thank you, adding define('DISALLOW_FILE_MODS', false); resolved the issue for me.

Your first solution worked perfectly for me. My website seemed to have been loaded with malware and I am trying to clean it. Some hacker did 150+ posts on my blog. Thank you so much.
