Error uploading a file

Good morning, I am exploring the omp but I have problems to changing the appearance of my website; when i try to upload the logo of the publication (.png), it is appeared an error in the file that says “No file is loaded or the file type is not valid”. Similarly it happens to me when I try to upload to custom style sheet or the main page image.Imagen%201Imagen%202

Is your public folder writable by a web server?

Yes, the public folder has write permission.

Hi @luzhelenah,

Check the FAQ area of this forum for a discussion of that error message.
