Unable to attach featured images to posts.

For some reason, I can’t upload any images via the add featured image section when adding/editing posts.

When I click add featured image, and then select upload, the page is just blank.

    Hello joejacobson

    I hope you’re well today and thank you for your question!

    It seems that the issue here is the Enhanced Media Library plugin which apparently isn’t compatible with WP starting from 5.3 release.

    I did some tests on your site (on main site and the “madel….” sub-site). The errors in the console suggest breaking two of the WP core JS scripts and initially pointed to one of three plugins – two related to classic editor (Classic Editor and Black TinyMCE) and the Enhance Media LIbrary. One of these errors could be fixed by actually configuring site to use SSL instead of being only redirected to SSL (changing http:// prefix to https:// prefix on Network Admin -> Sites -> [Edit for the site] – >Settings) but that didn’t solve the issue.

    However, when I temporarily disabled (it’s enabled back currently) the Enhanced Media Library plugin, the error was gone and the upload started to work.

    I check the plugin itself and apparently there are numerous reports on the very same issue, for example:

    https://wordpress.org/support/topic/5-3-crashes/

    https://wordpress.org/support/topic/potential-fix-wordpress-5-3-conflict-compatibility-error/

    But based on the topics on the support forum here

    https://wordpress.org/support/plugin/enhanced-media-library/

    I wouldn’t expect a fix anytime soon, I’m afraid. One of the users there suggested a replacement plugin:

    I’m not familiar with it but it looks to be quite popular, well-rated and, at least, under active development so I think you might want to give it a try.

    Best regards,
    Adam
