Hi Joe,
JCE uses its own upload handler, whereas image uploads in Joomla modules and the Media Manager use Joomla’s native upload process. As a result, they are subject to your PHP and server upload limits.
I can’t access your site’s administrator area to check the current upload settings, but you can verify them here:
Administrator → Content → Media
Check the following settings:
- Maximum Size (MB)
- Allowed Extensions
If those settings look correct, the issue is most likely caused by your server’s PHP configuration. Please check the following PHP values:
upload_max_filesize
post_max_size
memory_limit
max_execution_time
max_input_time
If any of these values are too low, you’ll need to increase them or contact your hosting provider to adjust the server configuration for you.
Please let us know what you find, and we’ll be happy to help further if needed.
