CiviCRM Community Forums (archive)

I just noticed that when I try to access the following pages:

1. Administer>CiviEvent>Participant Listing Options
2. Administer>CiviEvent>Event Types
3. Administer>CiviEvent>Participant Roles

As well as a few other pages, I get the following error message:

Fatal error: Class 'CRM_Core_DAO_OptionValue' not found in /home/(accountname)/domains/domain.com/public_html/sites/all/modules/civicrm/CRM/Core/OptionValue.php on line 100

(account information edited in the above error message)

What is happening?

As a side note, could whatever is causing that error message be related to another issue I outlined in another thread, located here:

http://forum.civicrm.org/index.php/topic,18902.0.html

Thank you in advance.

That error would suggest that you have a core CiviCRM file missing from your install. That file being of course:

Code: [Select]

CRM/Core/DAO/OptionValue.php
Can you check to see if you have that file? The full path would be:

Code: [Select]

sites/all/modules/civicrm/CRM/Core/DAO/OptionValue.php
If it's missing, then I would suggest you try to replace your entire CiviCRM code base to make sure all files are there.

Yeah, it's there. Thanks for responding.
