Hi,
1) If you have a blank page instead of your site there must be logs on the server or in your site’s root directory – error_log file, it is necessary to check it.
Besides, in your wp-config.php file in your site’s root directory you can change the line
define(‘WP_DEBUG’, false);
for
define(‘WP_DEBUG’, true);
and check if there are any errors on the screen (a blank page).
2) Either one of the installed plugins or your theme can cause the conflict. Please deactivate all the plugins except gallery and then activate them one-by-one in order to find out the plugin that causes the conflict.
Please try to install a standard wp theme (2012, 2013) and check if the problem remains the same.
3) As the custom uploader’s functionality primarily posts files into the plugin’s folder instead of uploads folder, and then when saving the post moves them to uploads folder using wp functionality, you should set 755 permissions to folders wp-content, plugins, gallery-plugin, upload, files. In such a case the plugin’s script will have enough permissions to upload images.
Please make use of the following documentation –

You can use a standard uploader on the same gallery editing page, and the uploaded images will appear in the block under the custom uploader.
Sincerely,
Support Team
