I found the error!
I changed the permissions of files and directories in my hospegadem.
Changed these permissions to 777, but the 755 is correct for directories and 644 for files.
Now the gallery is not mangled.
But an error still persists: when i click image to open large “X” to close the window is still “shaking” and the click does not work.
Also need to click to open the large image, you can continue navigating through large images, it is possible?
Can you help?
