 Most Common problems and their solutions

“Please enter your password.”

If you do not know your password and have given an email address to the library, click the "Forgot your password?" link on the Patron Login Page.  If you do not have a password for your account, click the "create a password" link on the Patron Login Page. 

“The system was unable to log you on, please check your barcode and password.”

This error occurs if an invalid barcode number, password, or both were entered.  Be sure to enter your entire barcode (all 14 digits) without any spaces or punctuation.  Be sure to retry your password.  Also remember that passwords are case sensitive: if you cannot recall your password, enter your barcode number and click Forgot Password.  Your password will be sent to the email address you have given the library.

 The system does not respond

If clicking “Log On” seems to do nothing or only refreshes the “Please enter your barcode number and password” screen, then accepting cookies may not by enabled in the patron’s Web browser. To enable cookies in Microsoft Internet Explorer 6.0, go to the Tools menu and choose Internet Options. Click on the Privacy tab, press the Default button and click OK.

This problem may also be caused by Personal Security (firewall) software.  To test, please disable your security and retry.  If the catalog works, please re-enable your security software, then visit or contact your technical support team to learn how to make MCLINC a trusted site, recognized by your browser in the future.
