This issue may or may not have to do with LiteSpeed.
Here are some suggestions that may help you to troubleshoot first:
Suggestion 1:
Put this in your themes function.php
add_filter( ‘wp_image_editors’, ‘change_graphic_lib’ );
function change_graphic_lib($array) {
return array( ‘WP_Image_Editor_GD’, ‘WP_Image_Editor_Imagick’ );
}
Suggestion 2:
Server configuration may not have the proper amount of memory allocated to Apache/PHP.
If anyone has this same problem, please try verifying that you have enough server memory allocation in your server configuration settings.
You can also add this to your wp-config.php file:
define(‘WP_MEMORY_LIMIT’, ’64MB’);
Suggestion 3:
Go to the /wp-content/ directory and see if the /uploads/ folder has been given the correct file permission.
If none of these suggestions work, please let us know.
