Try to delete the content of cache and compiled folder by FTP.

[reyko]

I go in root/public_html/cache.There is a lot of files also is htaccess.

Al of that files I must delete?

[effi]

Yes, you keep only htaccess, and delete too compiled folder content except htaccess
Don't mind, theY will regenErate automatically when you will come back to your website.
One file is probably corrupted

I think that you may have to change the permisions of the cache folder. The application does not able to delete files from the cache folder.

Indeed, I'm not linux professional, I hope one of our friends here able to till you how to do this task, or you may try to use your hosting account's cPanel.
