Enable Error Logging

I got this message when trying to use the DropBox plugin:

An error has occurred in Omeka. To track the contents of this error, please enable error logging.

How to enable the error logging?

Thanks,
kariv

Set log.errors = true in application/config/config.ini .

Okay, I'm having the same problem, but cannot seem to enable logging. My config.ini file is set properly, but I still get the "An error has occurred in Omeka. To track the contents of this error, please enable error logging." message. Where am I going astray?

Nevermind. Everything seems to work now.

Hi - I changed my config to log.errors=true and I am still getting this error message. Is there something else I should be changing?

Just a note after solving nderise's problem -- turning on error logging doesn't display errors on the screen; it generates an error file in the directory /application/logs/. The errors in this case were (falsely) unrecognized MIME types.

I solved nderise's problem by going to Settings --> Security Settings and clicking the checkbox labeled "Disable File Upload Validation / Check this field if you would like to allow any file to be uploaded to Omeka." The error is discussed here http://omeka.org/forums/topic/dropbox-errors and here http://omeka.org/forums/topic/file-upload-failed-mime-type-coulndt-be-deteced-for-jpeg-images

@amandafrench - You're right that turning on error_logging doesn't display errors on the screen. You can display errors on the screen by setting 'display_errors' to true in 'application/config/config.ini'. We didn't make this clear in our documentation page on Retrieving Errors, but I've updated that page. If I need to make those instructions clearer, please let me know.
