Few weeks ago, I upgraded WP mu for the websites that I am developing based on WP mu. After upgrading, I got the following message.
"The wp-content/blogs.php file is deprecated. Please remove it and update your server rewrite rules to use wp-includes/ms-files.php instead."
So, as the message says, I removed wp-content/blogs.php file and rewrote rules to use wp-includes/ms-files.php in the "htaccess file", as many people suggested. But, when I did that, all images that I have uploaded were gone. So, I reverted blogs.php file, then the images are appeared again.
My main concern with the error message is that the WordPress sites that I'm handling aren’t working like they should— I’m afraid that if I update the sites and a newer version of WordPress is released, I will be still stuck trying to figure out the problems with the older version and won’t be able to move forward.
Do you guys have any idea to fix this issue?
I look forward to hear any suggestions.
Thanks in advance.
