I have a simple Drupal site that has everything working before, but all of a sudden it started to fall apart with many places returning the above error. Most of the time the error shows up when clicking on the "Read more" or "Comments" on the bottom of each block that used to display the full content of the block on another page. There are also reminders that a few upgrades are available. At the worst situation, clicking on the "available upgrades" tab also resulted in the same error listed in the title.

One Drupal discussion said that clearing the cache in the module can solve the problem. I have cleared the cache in the "configure" page for "jQuery Update" and in the view module, and after that, clicking on the "available upgrades" tab resulted in the update information rather than the error. But the above error is still there when clicking on the "Read more" in the main page.

One other discussion (http://drupal.org/node/1190758) discussed exactly the same error, and the solution suggested was to switch the Accordion style from the default value of "Content" to "Fields". I checked the "Module" setting and the "view" module, but cannot even see anywhere that has an "Accordion style" setting. Could anyone tell me where the "Accordion style" setting is?

In the Module page, I see "view" and "view UI" modules installed, there's only a permission setting to it. I have also checked the "jQuery Update", and there's no related "Accordion style" setting either. I have "view" module version 7.x-3.0, while the latest Drupal upgrade available is 7.x-3.3, is it worth upgrading? If I need to upgrade the "view" module, do I really need to backup all my contents? Isn't that the Drupal site already doing periodic backup of the user content?

Details of the Drupal I am using:
- D7.x (upgraded from D6.x about a month ago, have not seen anything wrong at the time of the upgrade)
- Currently used functionalities: articles, photos, videos, Forum, blog, link to Google Doc, Facebook, etc.

Thanks!

based on the link you provided and the issue queue the post in is the accordion style would be within the views accordion module. Do you have that module installed?

I do not have that module.

In the View section, I only have "view" and "view UI", and both are enabled.

In that case switching to accordion style isn't likely to fix the issue you are having. you're looking for an issue in the views.module queue rather than the views accordion issue queue.

A drupal site does not automagically back up content. That's something you do with the backup migrate module, drush, via a tool like phpmyadmin, or directly from the command line. That said, when updating a module backups of the DB and the module being replaced is always a prudent idea and a best practice.

Thanks again, VM!

Then what would be the likely cause of this type of fatal error? Do you have any suggestions on how to resolve the error in the title?

did you clear cache in administer -> performance? I don't know what jquery update cache clear is, I don't use it. Not sure it's a necessity with D7 at all.

I cleaned cache from "configuration"->"Performance"->"clean all cache".
