Hi Steven,

Recently I have not been able to upload images into our Connections online directory. When I try to upload an image, I get the following alert popup: “Selected image exceeds maximum upload file size of 0 TB. Please choose a different image.” I see that a similar problem was addressed in this forum at the link below, but I did not see a solution to the issue: http://connections-pro.com/support/topic/maximum-upload-file-size-wrong/

We have been trying to allow larger file size uploads for our Multisite users, but I’m not sure how increasing file upload size would have broken the image upload feature in Connections. I was wondering if you might have any ideas please as to a solution; we need to be able to upload images into our directory.

Thank you!

Connections uses the core WP function wp_max_upload_size() to determine the max upload size of a file.

This core WP function uses the smallest of the server PHP environment vars upload_max_filesize and post_max_size.

One of those two seem to be set to 0TB.

Take a read of this tutorial:
https://kinsta.com/blog/increasing-the-maximum-upload-size-in-wordpress/

It seems pretty accurate as most do not even mention that post_max_size needs to be large than upload_max_filesize (not by much 1MB s/b more than plenty).

Also, I high recommend making the max less than the memory_limit value. Images when opened for processing such as scaling/cropping can take 3—5 times the available memory.

Hope this helps, let me know.

Thanks for your help Steven – I read through the tutorial and implemented the changes without success. I still get the message indicating that files larger than 0 TB cannot be uploaded. Any other ideas? What I have implemented is detailed below. Thank you! I have increased memory as follows:

-==[ PHP.INI FILE EDITS (/etc/php.ini) ]==-
post_max_size = 70M
upload_max_filesize = 65M
memory_limit = 128M


-==[ .HTACCESS FILE EDITS ]==-
# Increase maximum upload time
# Source: https://kinsta.com/blog/increasing-the-maximum-upload-size-in-wordpress
php_value upload_max_filesize 65M
php_value post_max_size 70M
php_value memory_limit 128M


-==[ WP-CONFIG.PHP FILE EDITS ]==-
// This might somehow increase the file upload limit in WP.
// Source: https://wordpress.org/support/topic/how-to-increase-the-max-upload-size
define('WP_MEMORY_LIMIT', '128M');

// More efforts to increase file upload size
// Source: https://kinsta.com/blog/increasing-the-maximum-upload-size-in-wordpress
@ini_set( 'upload_max_size' , '65M' );
@ini_set( 'post_max_size', '70M');
@ini_set( 'memory_limit', '128M' );

Well…everything looks correct but WP is still reporting 0TB. If you can give me an FTP login, I can take a closer look.

The cause is the the ../wp-includes/default-constants.php seems to have been replaced with either an older or an altered version. The file being used does not include new constants included in WP 4.4 for byte sizes. They are; KB_IN_BYTES, MB_IN_BYTES, GB_IN_BYTES and TB_IN_BYTES.

Because those constants were not set it would cause the core WP function wp_max_upload_size() to return a 0 value. Fortunately the wp_max_upload_size() function includes a filter named upload_size_limit.

Add added a new filter in the ../wp-content/plugins/connections/includes/inc.plugin-compatibility.php which check for those constants and then set them so the wp_max_upload_size() function will function correctly.

This should resolve the upload issue. Hope that helps!

@Steven – THANK YOU SO VERY MUCH!!! I owe you a beer or three! I’m not sure why the default-constants.php file is not the most recent… I’ll look into that.

Thank you!
