How to turn on "development" mode in Omeka Classic for error reporting

If you are working with Omeka and it’s not behaving properly, you can get a more detailed error message by turning on “development” mode. Below are the steps you can take to get that configured on your Omeka site for troubleshooting.

Show Hidden Files

To turn on robust error messages, make sure you login to your cPanel account and update your File Manager to show hidden files. You can do this by:

Click the settings icon at the top right of your screen:


Next click “show hidden files” and then click save:


Omeka .htaccess Changes

You will then open the .htaccess file in the root of your Omeka installation. Find the following line, and uncomment it (that is, remove the # sign): #SetEnv APPLICATION_ENV development . When you are done, it should read SetEnv APPLICATION_ENV development .


Once that’s done, reload your site and you should see an in-depth error on the page.
