Hello,
This plugin works fine alone with WordPress.
Please go through standard testing of themes and plugins (deactivate all others, use twentyfifteen theme, then turn on one by one, testing to find when the conflict arises – it is likely some kind of media related plugin or even your theme).
If you can isolate what is causing it in your case, I can find out why and possibly help you with a solution.
There is one known conflict with Media Library Assistant Plugin, which is an easy fix:
“you need to add the mime type for svg and svgz to MLA Settings –> Media Library Assistant –> Uploads (tab) and then it works.”
As this topic is marked resolved because the title is about the plugin working, please start a new one based on the particular conflict so it will help anyone else in the future when we post the fix.
Cheers
Ben
