Repetitive Php Error In Apache Error Log

by May 28, 2015

I am running Up.Time 7.4 on linux.  The apache error log is filling-up with this repetitive error message:

 

[Wed May 27 13:16:34 2015] [error] [client 10.76.244.12] stristr(): Empty needle – /usr/local/uptime/GUI/classes/user/UserLogin.inc:99 trace: #0 [internal function]: exception_error_handler(2, ‘stristr(): Empt…’, ‘/usr/local/upti…’, 99, Array)n#1 /usr/local/uptime/GUI/classes/user/UserLogin.inc(99): stristr(”, ”)n#2 /usr/local/uptime/GUI/classes/user/UserLogin.inc(56): UserLogin->getRedirectLocation()n#3 /usr/local/uptime/GUI/index.php(93): UserLogin->renderRedirectLink()n#4 {main}

I tried to examine the UserLogin.inc file, but it’s an unformatted mess.

 

Any ideas?
