Not all images are display

[MrSegler]

I am using the latest files for the Responsive File Manager, the version of PHP is 8.2

When I try to upload a file, I receive a message with : Unknown Error

But the fact is that the files are uploaded to the source folder. I see it when I open the FTP.

I don't see all the images when I want to insert a file. I am using it with TinyMCE.

You see that there are 18 files in the folder, but only 5 are displayed.

All the files are jpg or png.

The problem was not there before, everything was working well.

I saw in the previous issues that someone has something similar with this one, and it said that it was the browser extensions, but he did not give more details.

Thanks for your precious help or advice
