JavaScript errors in admin panel after update to 4.1

  • Hi,I’ve recently (2days ago) updated my WP website to 4.1, using automatic update option. I’ve also updated all plugins and themes on the website.

    Now, on several pages of admin panel, mostly which are related to template layout (like Edit Post) I’m getting JS errors, which results in lack of functionality of those pages. For example, I cannot set my front page Posts to be fullwidth – and it’s Very bad, since I have A Lot of traffic for this page, which is broken now…

    Any help will be highly appreciated

  • Have you tried disabling all plugins and reactivating one by one to see if an active plugin may be causing conflicts with the WP update? I would start there, it’s possible a plugin you’re using on site has not been updated to work with the current version of WordPress and causing issues? I hope this helps target the issue.

    Well, I did this but with no success..

    I actually found a solution, but it’s really only a patch, to get my site to work somehow:
    1)
    downgrade jQuery version – changed in /wp-includes/script-loader.php from local jquery.js (ver 1.11.1) to //ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js, the one that was before.

    2)
    found and fixed (after like 4hrs of debugging) a coding error in my old theme

    I assume it’s all because I run very old theme (Choices by https://www.kriesi.at/ ). Also the previous guy, who worked on this site did a lot hardcoding etc. Which doesn’t make upgrading easier..

    Sounds like you should find a new theme?

    Agree, but since current one was changed a lot, including hardcoding things in templates, I think it will be very hard to copy all the settings to a new one. I’m really only a few weeks working on WP and don’t know how to switch to totally new theme and keep my settings.

    Theme settings are theme-specific so no, you won’t be able to “keep” them. What you may want to do is make a copy of your site in a separate WP install in a sub-directory and start working on the new version while leaving the old one up until you’re ready to go.

    Check out the Duplicator plugin for copying the site.
