I don't have permission to adopt pets FROM MY SITE?

[LUC1G07CH1]

It just happenend when i just have added a mod.

Well...I had trying to adopt from my site,but it says "an error has occurred.
It appears that you do not have permission to adopt"

And i have seen the admin pannel and it says some thing like this too: "You do not have permission to access Admin Control Panel.
"

How we fix that? Sorry but MY site hates me? I don't know?

Edit: I have placed the unban thing,but i'm still banned...I tried again but there's a error. Message:
Parse error: syntax error, unexpected ']' in /home/enchante/public_html/functions/functions_users.php on line 125

Edit²: It gives me another message...Warning: PDO::__construct(): php_network_getaddresses: getaddrinfo failed: Name or service not known in /home/enchante/public_html/classes/class_database.php on line 57
