<p>Recent minor updates for WordPress introduced a couple of regressions when uploading audio and video files:</p>
<ul>
<li>
<p>On WordPress 4.3.x and earlier branches, audio/video files cannot be uploaded at all due to a fatal error.</p>
<p>Full list of affected versions: 3.7.19, 3.8.19, 3.9.17, 4.0.16, 4.1.16, 4.2.13, 4.3.9.</p>
<p>This will be fixed in the next minor update, see the <a href="https://core.trac.wordpress.org/ticket/40085" rel="nofollow ugc">Trac ticket #40085</a>.</p>
</li>
<li>
<p>On WordPress 4.4.x and later branches, audio/video files are uploaded with corrupted thumbnails.</p>
<p>Full list of affected versions: 4.4.8, 4.5.7, 4.6.4, 4.7.3.</p>
<p>This will be fixed in the next minor update, see the <a href="https://core.trac.wordpress.org/ticket/40075" rel="nofollow ugc">Trac ticket #40075</a>.</p>
</li>
</ul>
<p>In the meantime, this plugin is a workaround that solves both issues and restores the upload functionality for audio and video files.</p>
<p>Don’t forget to remove the plugin once the next minor WordPress update is available!</p>

<h3>WordPress File Upload Types Plugin</h3>
<p>Do you want to let your WordPress website accept uploads from your users for more file types and to freely upload files? We created the File Upload Types plugin to make it simple for anyone to easily add support for any file types with any extension or MIME type.</p>
<h4>How WordPress File Uploads Work</h4>
<p>By default, WordPress only allows <a href="https://codex.wordpress.org/Uploading_Files#About_Uploading_Files_on_Dashboard" rel="nofollow ugc">certain file types</a> to be uploaded to your website’s media library.</p>
<p>If someone tries to upload a file type outside of these whitelisted WordPress file extensions, this can be the cause of the <a href="https://www.wpbeginner.com/common-wordpress-errors-and-how-to-fix-them/?utm_source=wprepo&utm_medium=link&utm_campaign=fileuploadtyes&utm_content=readme" title="common WordPress error" rel="friend nofollow ugc">common WordPress error</a> <code>Sorry, this file type is not permitted for security reasons</code> message.</p>
<p>It can be frustrating if you’ve <a href="https://wpforms.com/how-to-create-a-file-upload-form-in-wordpress/?utm_source=wprepo&utm_medium=link&utm_campaign=fileuploadtypes&utm_content=readme" rel="friend" title="
created a file upload form">created a file upload form</a> in WordPress but the file type you want to accept is a file extension that’s not allowed.</p>
<p>This plugin lets your website upload more file types beyond the limited file extension types that WordPress allows by default.</p>
<h4>How does the File Upload Types plugin work?</h4>
<p>The File Upload Types plugin works by letting you adjust the internal file whitelist, letting you manually control which types of file extensions your WordPress website can upload.</p>
<p>This way, you can accept any file type through your website and/or any contact form plugin like <a href="https://www.wpforms.com/?utm_source=wprepo&utm_medium=link&utm_campaign=fileuploadtypes&utm_content=readme" title="WPForms" rel="friend nofollow ugc">WPForms</a>.</p>
<h4>What file types can I upload to WordPress with this plugin?</h4>
<p>The File Upload Types plugin lets you allow uploads of any file extension, including custom file types.</p>
<p>Some common file extension types this plugin lets you add that WordPress doesn’t support natively include:</p>
<p>.ai<br />
.zip<br />
.xml<br />
.svg<br />
.csv<br />
.mobi<br />
.cad<br />
.dwg<br />
.dxf</p>
<p>…and any other file extensions that exist, including custom file types.</p>
<p>We hope that you find the File Upload Types plugin helpful!</p>

File Upload Types by WPForms

I got it to allow ePub uploads easy. I just had to get the mine type right, which I bet can sometimes be a bit tricky and texhnical. But the plugin dies it’s best to make that as simple as possible.

Thanks!

Worked great
