Question Can't Log Into Front End

I using the latest version of J 3.3.0 and PHP 5.3.28 My forum has very little activity and I have not logged in for a while. Today, when I entered my UN & Password I received an error that prevented me from logging in from the front end. I updated Kunena to 3.0.5 but I'm still getting this message:

Error

JAuthentication: :authenticate: Failed to load plugin: plgauthenticationcookie

Failed to authenticate: Access Denied

Any help would be greatly appreciated

Thanks for the link. I read through the thread and I have not resolved my issue. I can log into the backend of the Joomla administrator, but I can't log into the front end of Kunena. I can log in to the front end of Kunena using other test accounts but not my primary account. The thread seems to suggest that changes need to be made to Authentication Plugins. I reviewed those and I think I made the appropriate changes. I have added a PDF with screen grabs of the plug in settings. Thanks again for your help.

Go to backend - kunena- users - see on your account, if its maybe disabled, or banned

Thanks for your reply. I looked at the User Manager and my account is Enabled and is marked as a Moderator

I think its a template issue.

Please change joomla template to Prostar and try again
