Ok it turns to be very annoying this :(

Look what happens. I upload at albums file as suggested a new file with pictures.

I go as usual press the button to upload and i have a blank page!

Then i can't even open my home page.

To solve this i have to close my browser, delete the templates_c files reopen the browser and if i try to repeat the procedure i have the same results.

In conclusion i can't upload pictures. I manage to upload two albums after many attempts :(

Is this something with the theme i use ?

look at my site please.
