WordPress 4.7.1 Uploading SVG bug

Recommended Posts


WordPress 4.7.1 was released on 11th January.

It introduced a new bug that stops certain filetypes from being uploaded.

This bug unfortunately stops users from uploading SVGs with the Platform 5 builder.

In the meantime if you need to upload an SVG or have any other image upload issues then please try this plugin that bypasses the mime checks that were introduced.


With the upgrade to WordPress 4.7.1, some non-image files fail to upload on certain server setups. This will be fixed in 4.7.3, see the Trac ticket.

In the meantime, this plugin is a workaround that disables the recently introduced strict MIME check to restore the upload functionality.

Don't forget to remove the plugin once WordPress 4.7.3 is available!

Link to trac ticket: https://core.trac.wordpress.org/ticket/39550

EDIT: 4.7.2 has been released without the fix. Fix is now slated for 4.7.3

4.7.2 released without fix. (see edit history)

Simon is that why I would be getting this message when trying to load paglines zip as a new theme 


Unpacking the package…

Installing the theme…

The package could not be installed. The theme is missing the style.css stylesheet.

Theme install failed.

      Hi everyone, since Instagram had allowed to publish in different ratio formats (instead of only square ratio) the grams stripe has different heights. Can you tell me if i can fix it easily with some CSS?
