Hi everyone,

We are using MediaPress on our web site, staging link, for example:
https://iceclogstage.wpengine.com/groups/icury/

So far we didn’t have big issues but after the latest WordPress + plugins update, seems like we are unable to upload any media. Textual posts are working properly but image posts are not working at all.

This is what we have from MediaPress debugger tool, if it helps.

Could you provide us with any insights on what this might be or how to debug it?
If needed I can provide you with admin access to staging environment so you can examine it on your own. I would need a reliable way to share credentials, not to post them here in public post.

Kind regards,
Milan
