recreating thumbnails shows white pictures

[rachengold]

Hi.

After having thumbnails recreated, thumbnails are white and pictures cannot be shown any more.
In backend, system says, that the thumbnails have been successfully recreated.
But, even here, the thumbnails are not shown. Instead, the message "image size increase" is shown.
If clicking on it, the system runs forever without any effect.

Joomla 3.3.6.
Phoca Gallery 4.1.2.

Thanks for help.

Solved.

Fore some reason, the recreating of thumbnails was disabled.
After enabling this, everything worked well.

Ok.
