Missing callback function – Can't update – Get warning message

    I am running OSX El-Kapitan and Firefox browser.

    I have a site at http://linesandlight.net/

    I logged in recently to update to WP 4.6

    I also wanted to update the Jetpack plugin from 4.1.1 to 4.2.1

    When I logged in and went to do the updates I received a line of dialogue:
    Warning: call_user_func_array() expects parameter 1 to be a vallid callback function “wp_resource_hints” not found or invalid function name.

    When I asked for further details I got:

    /home/hawcroft/public-html/linesandlight.net/wp-includes/plugin.php on line 525

    Neither the Jetpack plugin or the WordPress app will update. I just get a spinning beachball and eventually I got a report from Wordfence:

    Wordfence found the following new issues on “Lines & Light”.
    Alert generated at Friday 19th of August 2016 at 10:31:25 AM
    Critical Problems:
    * WordPress core file modified: readme.html

    Unfortunately, the only backup of the site I have is from when I first set it up – I normally have auto backup turned on but somehow hadn’t done so with this site so although I can restore, it loses virtually all content since April.

    I’m not IT smart [clearly] so if anyone can suggest a solution I can implement without having to start again, it would be great.

    If I’m being an idiot and posting in the wrong place or asking a stupid question – please accept my apologies. I do try to fix things myself before yelling for help but most of it is beyond my knowledge or competence.

    Have you considered updating WP and plugins manually?

    WordPress:
    Download a fresh copy of the WordPress .zip file to your computer, unzip it, and use that to copy up all files and folders EXCEPT the wp-config.php file and the /wp-content/ directory. You may need to delete the old wp-admin and wp-includes folders and files on your server before uploading the new ones. Please read the Manual Update directions first.

    Backup: If you haven’t already done, always backup everything (including your database) before doing any actions, just in case something really goes wrong. You can never have enough backups!

    Tara,
    Thank you so much for your help. I had a little difficulty but your advice got me through and I now have my site both updated and back up and running smoothly. I have also made sure that I have a BACKUP – of everything.

    I am really very grateful for your assistance – it’s a site I built for my wife so you’ve kept me out of the doghouse and I’ve also learned some things I hadn’t realised before.

    Your response was very kind – thank you for taking the time and trouble to help. If there is anything that acknowledges your contribution of the member of the forum, I’m happy to give it – for now, YOU ROCK!
