sathyabhat on "[Plugin: WP Attachments] WP-Attachment doesn't attach the files, shows 500 Internal server error"

I have a 4.3.1 multisite setup consisting of 2 sites. If I click on Post New - Attach media, WP Attachments doesn't attach the file from media library on to the post.

From developer console, I see this error when I click on New Post/Edit post:

GET http://new.cbps.in/wp-content/plugins/wp-attachments/inc/styles/ij-post-attachments.css?ver=9c1fa12f1383596399a5393a6a5010eb 500 (Internal Server Error) post-new.php:51

line 51 on post-new.php corresponds to:

<link rel='stylesheet' id='ij-post-attachments-css' href='http://new.cbps.in/wp-content/plugins/wp-attachments/inc/styles/ij-post-attachments.css?ver=9c1fa12f1383596399a5393a6a5010eb' type='text/css' media='all' />

I can, however, attach the file from Media Library - Attach byutton.

Any idea why this is so?

Thanks
