Thanks for the help.
I did the php cheking and when i click on repair table, this error appears: "#1142 - INSERT command denied to user 'javmar_javmar'@'184.108.40.206' for table 'pixelpost_addons'"
Then I made the http://www.javimartin.es/admin/install.php
installation and it was ok. But at the end it changed to upgrade window but nothing was shown. Just the pixelpost upgrade window without any information.
