Upgrade to 4.4.1 causes site icon issues for Multisite installs

[jshare]

I just upgraded my Multisite install to 4.4.1 yesterday. Later in the day I received a ZoompfAlert with two warnings:

404 response for jobmob.co.il/wp-content/uploads/2015/08/cropped-site-icon-32x32.png

404 response for jobmob.co.il/wp-content/uploads/2015/08/cropped-site-icon-192x192.png

Zoompf sends that alert because its bot discovered calls on my site to those urls but gets 404s.

However, as I'm on Multisite, those images do exist here:

jobmob.co.il/wp-content/blogs.dir/1/files/2015/08/cropped-site-icon-32x32.png

jobmob.co.il/wp-content/blogs.dir/1/files/2015/08/cropped-site-icon-192x192.png

So somewhere on my site since the upgrade to 4.4.1, non-Multisite compatible calls are being to these images.

Thanks for the report @jshare.

The wp-content/uploads/... URLs are automatically rewritten to wp-content/blogs.dir/xxx/files/....

• Did you make any changes to your HTTPS configuration recently?
• What's the value of the ms_files_rewriting row in your wp_sitemeta database table?
• Are you defining any of the following constants in your wp-config.php file?
  • UPLOADBLOGSDIR
  • UPLOADS
  • BLOGUPLOADDIR

No

There are 154 rows in my wp_sitemeta, but no ms_files_rewriting or *files* or *rewriting*

• Are you defining any of the following constants in your wp-config.php file?
  • UPLOADBLOGSDIR
  • UPLOADS
  • BLOGUPLOADDIR

No

Any news?

@jshare are you still experiencing this issue?

Thanks for the reminder, I forgot about this.

It turns out this was related to two Site settings being out of synch (in the Network Dashboard > Sites > (relevant Site) > Settings:

1. Upload Path
2. Fileupload Url

The latter was set correctly to 'jobmob.co.il/files, but the former was set to 'wp-content/uploads' when I needed it to be 'files'.

Either the upgrade to 4.4.1 put them out of synch or it simply exposed that they were already out of synch and it hadn't mattered before the Site Icon functionality.

All working fine now :)
