WordPress 3.0 Problems And Their Solutions

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!
