Support » Installing WordPress » Upgrade from WP 3.1.4 to WP 3.2 – Admin error: Cannot redeclare get_temp_dir()

  • Resolved Mark


    I’ve upgraded a couple sites from WP 3.1.4 to 3.2 without problems. However, one site generates this error:

    “Fatal Error: Cannot redeclare get_temp_dir() (previously declared in /home/public_html/wp-includes/functions.php:2160) in /home/public_html/wp-admin/includes/file.php on line 189

    If I comment out the function in functions.php I can then access the admin panel and finish the upgrade. Then when I uncomment the function the site crashes again when accessing the admin panel.

    Anyone have a clue why is this happening?

  • So here’s the solution:

    Reinstall all WP core files.

    So here’s the reason it happens:

    Automatic upgrade automatically fails when it can’t automatically do everything it needs to automatically do. In some cases we wind up with half a copy of WP 3.1.4 files and half a copy of WP 3.2 files. Not good.

    Anyway. Problem discovered and solved 🙂

    How do you reinstall all WP core files? And which are the core files? I’m having the same problem.

    The WP core files are all the files that come in the zip download:

    Unzip that to your local system, then FTP all the files and dirs up to your live site.

    Oh, thanks. Worked! Whew.

    Will this take out all the posts i had previously made, themes, etc?

    I managed to keep the plugins, themes and content. Just deleted WP-Admin and uploaded the fresh version and the same for the functions.php. The rest was left as is.

    For me this happened on BlueHost and I have a feeling it has to do with their auto script even though I manually installed this particular site.



    Thank you! I also swapped out the WP files in the wp-admin and wp-includes folder. That’s all it took!

    thanks for the tip, yes I also did the same as above, but only uploaded the new WP-Admin, which replaced the old works great now.

    thanks again
