After installation, the error message occur

Warning: file /web/php/literacy/administrator/components/com_comprofiler/pluginsfiles.tgz still exists. This is probably due to the fact that first installation step did not complete, or second installation step did not take place. If you are sure that first step has been performed, you need to execute second installation step before using CB. You can do this now by clicking here: please click here to continue next and last installation step.


But I press the continue link, the page return blank.
