This is my first time using WordPress. My client hired someone to create a site for him with a custom template in wordpress and he is hiring me to finish the site. I tried to update wordpress yesterday to the latest version and clicked to update all plugins, and I’m not sure the update was successful. Since then, when I go to the log in screen I see this at the top:
Warning: call_user_func_array() expects parameter 1 to be a valid callback, function ‘sanitize_comment_cookies’ not found or invalid function name in /home/content/92/10622692/html/tmp/wp-includes/plugin.php on line 406
Fatal error: Call to undefined function wp_count_comments() in /home/content/92/10622692/html/tmp/wp-admin/menu.php on line 94
When I go to the homepage online I see: the same error throughout the homepage.
Check it out:
I am concerned that I can’t even get into the code to fix anything…
Are these theme specific errors?
Try switching to the default TwentyTwelve theme and see if the errors persist. If they do not, you know it’s a theme issue.
I’m not sure how to change the theme because I can’t log in. It very well may be a theme issue. This site is using a custom theme (that I didn’t create) and updating the plugins/wordpress may have caused a problem.
Try switching to the default theme by renaming your current theme’s folder inside wp-content/themes and adding “-old” to the end of the folder name using FTP or whatever file management application your host provides
I had to restore my files for the site to before the updates and my site is back. I updated wordpress alone and I am still working, so that wasn’t the problem. It must have been one of the plugins clashing with the custom template. I will update them one by one until I find the problem!
