[SOLVED][Drupal CKEditor] CKEditor not working in IE8

| | 1 min read

A few Drupal users noticed that their CKEditor was not working in IE8. They had also noticed that the Debug Bar they had used was showing the error "Line 11 - Error Insufficient memory to continue this operation." The IE8 debugger tool also showed the following errors 'Drupal' is undefined on line 21, 25 and 28 in ckeditor.config.js & "insufficient memory' on line 11 in ckeditor.js". If you are facing the same issue in your Drupal site when using IE8 then read on.

This error occurs if the CSS files are not compressed. Here are the steps to fix the issue.

  • Go to Admin/Settings/Performance/ in your Drupal site.
  • Go to Optimize CSS Files and click on Activate

Hope that helps.
