Bug description

To my knowledge, this is not a PHP or server issue. I am able to upload images and other documents to my main Nextcloud file system. The issue arises when an image is uploaded to a markdown document using Nextcloud's built-in markdown editor. When an image is uploaded, a simple "Upload error" appears in the top right corner of my screen. Upon further inspection of the logs, I see the following response:

Maximum number of allowable file uploads has been exceeded at Unknown#0

This would lead me to believe that there is something wrong with my install / PHP settings specifically, but as I mentioned earlier, I am able to upload any number of documents and images to my Nextcloud file section.

I am currently on the latest version, Nextcloud Hub 4 (26.0.0)

Steps to reproduce

1. Create a document in Markdown
2. Attempt to upload an image using the built-in WYSIWYG editor

Expected behavior

An image is successfully inserted into the markdown document

This error is issued by PHP so it looks like a setup issue. You might want to check the value of max_file_uploads in your php configuration.
