Page without the admin doesn't open bitrix?

What could be the reason if the page without the admin doesn't open and gives net::ERR_CONTENT_DECODING_FAILED and in admin interface opens. When you reset the entire cache without the admin panel will open once, and then again becomes unavailable?

1) Check the server script bitrix_server_test
2) Check the server through the built-in test site
3) Disable the compression module, if equipped

2). Check the permissions on the folders, especially in the /bitrix/cache/
