[isf-wifidog] Portal crashes on login

[Jan Lühr]

Hello,

every time I try to login, the portal throws an error-Message:

execSqlUpdate() : An error occured while executing the following SQL query :
DELETE FROM connections USING tokens WHERE 
tokens.token_id=connections.token_id AND token_status='UNUSED' AND user_id = 
'35af1963f47ef3968cab3bdd835cd799'; INSERT INTO tokens (token_owner, 
token_issuer, token_id, token_status) VALUES 
('35af1963f47ef3968cab3bdd835cd799', '35af1963f47ef3968cab3bdd835cd799',
