2. In the top bar, click on ‘Options’

3. Within the options tab, scroll approximately half way down the page to ‘post_max_size’ and set the value to 128MB or higher if required

4. Scroll to the bottom of the page and increase the ‘upload_max_filesize’ to 128MB or higher if required

5. Go into your CMS (Content Management System) such as WordPress, and verify the maximum upload size for your files has increased
