WordPress 3.0 Problems And Their Solutions

by

WordPress 3.0Earlier we saw the fix for WordPress Error – Headers Already Sent Warning Problem and also WP Super Cache Content Encoding Error. Now we are going to discuss about the common problems and solutions in the much awaited WordPress release, WordPress 3.0, which released last week and reached maximum of downloads. WP 3.0 had several fixes and new features, but unfortunately some of the themes were not compatible with WordPress 3.0 and famous Thesis was one amongst them I believe.

#1 – Problem : Custom File Editor Issue in Thesis 1.7

Error :

Fatal error: Call to undefined function use_codepress() in /home/content/46/5420546/html/wp-content/themes/thesis_17/lib/admin/admin.php on line 42

Solution :

Just follow these steps and please don’t forget to keep a backup. Please!

  1. Connect to your webhost using FTP Client or CPanel File Manager. I recommend FTP Client, and preferably FileZilla.

  2. Go to the location mentioned in the error message

Example : wp-content/themes/thesis_17/lib/admin/

  1. Download admin.php to your system and open it using a file editor. I recommend NotePad++.

  • Now go to the line 42 (where the error is) and add two forward slashes before it and make that as a comment.

    • Example : //if (use_codepress()) add_action('admin_print_footer_scripts', 'codepress_footer_js');

    1. Now upload the updated admin.php to the wp-content/themes/thesis_17/lib/admin/ and that’s it!

    Now you can use the Custom File Editor without any issues, but you’ll unfortunately miss syntax highlighting feature. Hope the next version of Thesis will solve this problem!

    10. Hi:

      Upgrading to WordPress 3.0 has made life really messy at our end. The following two are the most frequent error messages that I get:

      1. For some reason, “Excerpt View” is not processing correctly and creating “Premature end of script headers” errors.

      [Wed Jul 07 03:16:59 2010] [error]
      Script timed out before returning headers: admin-ajax.php,
      referer: url/wp-admin/edit.php?mode=excerpt

      2. Our pages are making an “inner join SQL” query – which did not exist earlier.

      The following has become REGULAR FEATURE now – thereby causing non-loading of site almost most of the day. The pages just keep on loading.

      3. error_log: Premature end of script headers: wp-cron.php
      &
      error_log: timed out before returning headers: wp-cron.php

      I would be pleased if you could share your thoughts on any possible troubleshooting for the above.

      Best,
      Anshuman

      • Screenshots will be great Himanshu. I can check where the problem is easily. 🙂

        To avoid such issues, most of the themes come with ie8.css file. You can report this to the theme author.

    13. Maybe we didn’t do something right, but two things are arie on our end as well when we opened [even] a new installation of wp3…

      when submitting ANYTHING with quotes in it… single/double… they’re submitted via the normal post wysiwyg [ or using html only ] editor and they return with the ‘s [backslashes] in them… and no only that… because of it… it’s not appearing properly in the posts/pages, etc…

      in addition – there are *MAJOR* issues with moving from visual html editor mode… it removes HREF/SRC urls entirely…

      i’m sure this is our fault,… or is it!? 🙂

      help?

    23. Thanks for all the info and detailed workaround for Thesis and WP 3.0. It is VERY helpful to all of us who are a bit challenged when it comes to coding, php and so on.

      Thesis is great, but I wish it was better equipped with push button customisation options rather than having to code certain things.

      It’s site like yours that make my day and take the headache away.

      Great post, thanks again

    28. Great post buddy, newbies are usually afraid to upgrade the blog because of several issues, it is good to see that you already found the solutions for them 😉

      Thanx!
