Error on Thumbnails

[jackwhite.com.br]

Hello, guys! I need your help!

I'm having issues when I'm trying to do some uploading on my Coppermine gallery (URL - http://jackwhite.com.br/galeria/).

This error appears when I try to send my photos:

Erro crítico
Impossível criar miniatura ou a imagem em tamanho reduzido.
Foto: /home/u544426983/public_html/galeria/db_input.php - Linha: 704
(in english it's says something about having trouble on making the thumbnails).

Here's the test user account data:
    Username: teste
    Password: 123456

I have been using the image taken from http://www.guitarlessons.com/wp-content/themes/glTemplate/images/guitarist/jack-white-thumb.png as an example to test with.

Having done as suggested in http://forum.coppermine-gallery.net/some_forum_thread didn't work as expected. ):

Thanks in advance for your suggestions!

Go in Config-General settings-Enable plugins and disable it.Then try to see if you still have the error.
If you don't have it then one of the plugins you installed is causing the problem.
I had a similar problem and was a plugin.

Now I use HTML5 multi-file upload plugin that is better then flash upload.

Doesn't work. Also user "test" and "tester" doesn't work, if "teste" is a typo.
