For some reason, ctools/includes/plugins.inc is requiring an .inc file that doesn’t exist (and doesn’t need to exist in this custom module, as far as I know), and on /admin/user/permissions, that’s what it’s blaming for the 500 error. Other admin pages are fine. This is also making drush throw a lot of errors on drush cc all.
Error in dblog and syslog:
require_once(./sites/SITENAME/modules/CUSTOM/MODULENAME/SundialParser.inc) [function.require-once]: failed to open stream: No such file or directory in D:\PATH\acquia-drupal-1.2.21\sites\SITENAME\modules\ctools\includes\plugins.inc on line 770.
PHP 5.2.17 PHP memory limit 256MB Ctools 6.x-1.12
Stuff I’ve tried that hasn’t worked:
- adding and enabling the filter permissions module
- changing the admin theme
- increasing php memory
- manually truncating cache tables
Existing discussions:
- Error 500 only on permissions page
