    Sorry to have to ask, but I can’t get to my blog and am getting very stressed now. I am new to WordPress, please bear this in mind.

    When I try to access my wp-admin dashboard thing to update my blog I get an error message: Fatal error: Call to undefined function wp_is_mobile() in D:\Hosting\9251946\html\tinteddy\wordpressdir\wp-admin\index.php on line 22

    I update WordPress to the lateset version yesterday evening, I can only assume that is what has caused this.

    I have read a couple of posts and tried the following.

    I renamed the themes folder as MYTHEME-old – still get same error
    I renamed the plugins folder as plugins.hold – still same error

    Again, I am a beginner with all this code stuff. If anyone could please give me some information on how to edti my blog I would be so grateful, it means a lot to me.

  • I am having same issues, so no resolution except deleting the install except the wp-content folder and then reinstalling WordPress? Seems extreme. Doesn’t WordPress have some sort of solution for this issues?

    That IS the solution….

    If you are having the exact same issue, that is

    Sometimes files get corrupted or missed – no fault of WordPress, and nothing that can be done aside from reinstalling the bad files

    I had same issue as TinTeddy had while updating to 3.4.1, then I tried the method that esmi suggested(delete wp-admin, wp-include folders and the root files, then upload the fresh files downloaded from WP), it works!!! Much appreciate you guys’ help to solve this problem!

    I tried this method and now I get this error when trying to login to WordPress:

    https://fitnessvortex.com/wp-admin/
    Warning: require(/home/content/f/v/s/fvsschone/html/wp-includes/class-wp-theme.php) [function.require]: failed to open stream: No such file or directory in /home/content/f/v/s/fvsschone/html/wp-settings.php on line 115

    f/v/s/fvsschone is something I setup with GoDaddy when starting the site. I’m freaking out. Please help.

    Great Help @esmi. Concise and to the point. Had me back up in running in 5min!

    Thanks

    I am having the same issue, but since I can’t log in to wp-admin, I can’t change my theme. This is my first WP publishing attempt. I used CyberDuck to transfer my files from localhost to host, and now when I try to login to mysite/wp-admin, I get this error:

    Fatal error: Call to undefined function wp_is_mobile() in /home/glenn235/public_html/wp-admin/index.php on line 24

    I don’t know how to fix this, and can’t log in. Also, I am not sure how to post my own thread/issue in this forum. This was the closest match I could find to my issue.
