Trouble new page and customizing Theme.

  • Hello,

    After updating to wordpress 4.0 I get two errors:

    When trying to add a new post I cant see what I’m typing and this errorcall is at the bottom :

    Fatal error: Call to undefined function get_editor_stylesheets() in /home/deb71900n2/domains/writingmonique.com/public_html/wp-includes/class-wp-editor.php on line 515

    And when I try to customize my theme I get this error in a new screen:

    Fatal error: Call to undefined method WP_Customize_Manager::add_panel() in /home/deb71900n2/domains/writingmonique.com/public_html/wp-includes/class-wp-customize-widgets.php on line 436

    Maybe its really simple, some sort of problem recognizing widgets ?

    I hope someone could help me. I’d really appreciate it.

    Thanks!

  • Hi…

    I would start with the simplest, easiest solution:

    Re-install the 4.0 wordpress bits. Sometimes the install gets corrupted for any of a number of reasons.

    Start with this…and see how you are after.

    If that doesn’t work, come on back and let’s talk next steps.

    Hope this helps…

    Fatal error in the output generally indicates either: (1) your theme doesn’t like your version of WordPress (2) you have a plugin that doesn’t like your version of WordPress (3) or you have an incomplete install/upgrade.

    Therefore, try a few basic troubleshooting steps:
    – Flushing any caching plugins you might be running, as well as server and/or browser caches.
    – deactivating ALL plugins temporarily to see if this resolves the problem. If this works, re-activate them individually (one-by-one) to find the problematic plugin(s). If you can’t get into your admin dashboard, try deactivating via FTP or SFTP or whatever file management application your host provides. Also remember to deactivate any plugins in the mu-plugins folder. The easiest way is to rename that folder to mu-plugins-old.
    – If that does not resolve the issue, try switching to the unedited default Twenty Fourteen Theme for a moment using the WP dashboard to rule out any theme-specific issue. If you don’t have access to your admin area, you can switch to the default theme by renaming your current theme’s folder in wp-content/themes and adding “-old” to the end of the folder name using via FTP or SFTP or whatever file management application your host provides. Alternately, you can remove other themes except the default theme. That will force your site to use it.
    – If that does not resolve the issue, try resetting the plugins foldervia FTP or SFTP or whatever file management application your host provides. Sometimes, an apparently inactive plugin can still cause problems (because the hooks remain unless plugins completely removed or some plugins stick around in cached files. So by renaming the folder, you break them and force them inactive).
    – If all the above steps do not resolve the issue, then try MANUALLY re-uploading all files and folders EXCEPT the wp-config.php file and the /wp-content/ directory from a fresh download of WordPress. Make sure that you delete the old copies of files & folder before uploading the new ones. Read the Manual Update directions first!
    – running the upgrade manually via wp-admin/upgrade.php
    – BTW, if you haven’t already done, always backup everything (including your database) before doing any actions, just in case something really goes wrong. It’s a great safety net.

    Thanks TychoMonolith and Tara, currently working on it ?? I did try the plugin and theme changing/shuttingoff before from reading it somewhere.

    But Ill try it more systematically again now and this time the mu-plugins as well.

    Itll probably end in the manual update. But hey it gets me learning.

    Many thanks for the tips!
