Thanks for your report. There are several SVG Support plugins in the WordPress Repository and I want to make sure I found the one you are using. I installed and activated this plugin:
SVG Support version 2.3.10 by Benbodhi.
Is that the one?
I ran a quick test and I was able to upload SVG files without any problems when both MLA and SVG Support are active. I was not able to reproduce your issue.
There are several ways to upload files, and I only tested the Media/Add New (Upload New Media) admin submenu screen. If you are having a problem with uploading files in some other way, give me more details about the steps you are using and I will investigate further.
MLA, by the way, also provides code that fixed the SVG upload problem introduced in WP 4.7.1.
Any additional information you can provide will be very helpful. Thanks for your interest in the plugin.
