Updating your Omeka file size upload limit is a small change that can be done fairly easily, and below are the steps required to make the necessary changes to have that setting adjusted.
We have documentation on how to access your File Manager for your website files.
Changes to config.ini
Next, you then want to navigate to your applications
/application/config/config.ini file. Right-click the file and select “edit” to then access the file editor where you will make the following changes.
Once you have the file opened, search the file for the line with
upload.maxFileSize = "10M" and uncomment the line, then update to your desired upload limit.
Save your changes, and that’s it!
