Hi pshowell,
You ALSO have to modify omeka’s “config.ini” file.
Omeka will allow for the least of php.ini and config.ini maximum files size.
The config.ini file should be found in “application/config” of your omeka’s installation.
For instance : /var/www/omeka/application/config/config.ini
upload.maxFileSize in config.ini is commented by default, so uncomment it, and put you desired max file size limit.
upload.maxFileSize = “10M”
(Also remember to restart your apache server )
I hope this helps.
Greetings
