Frequently Asked Questions
What does 'invalid redirect_uri' mean when installing the Mendeley plugin?
This error typically means there is a misconfiguration between Mendeley's authentication servers and the Microsoft Word add-in portal. It prevents the login page from correctly sending you back to Word after you enter your credentials.
Can clearing my browser cache fix the Mendeley installation error?
While clearing your browser cache can sometimes resolve login loops, the 'invalid redirect_uri' error is usually a backend issue. If basic troubleshooting fails, it is best to contact Mendeley support for assistance.
Are there other citation managers I can use in Word if Mendeley fails?
Yes, if the Mendeley plugin is temporarily unavailable, you can use other popular reference management tools like Zotero or EndNote, both of which offer dedicated plugins for Microsoft Word.
