I filled out a support ticket on this as well, but thought I would post here to see if someone on this board could help quicker.

I just upgraded to the latest version 7.5.4.2 and the upgrade appeared to complete successfully, however, now no one can log in...including myself as Admin. I have tried clearing browser caches, checked permissions on the folders, double checked the sql database info and have cleared all the files from the sessions folder. None of these have solved the problem.
Anyone have other suggestions I should try?
Thanks in advance for your thoughts!

Forgot to add that the message I receive is just "Access Denied" when trying to log in. From what I can tell the settings are correctly pointing to the database in the config file.

Hmm, will check your support ticket. That's an odd message to be displayed upon login.

I don't understand exactly what was wrong, but Rick has me fixed back up and running again! Thanks Rick!

I am having the same issue. Any thoughts on this?

Same Issue here too.

Quick search of the 7.5.5 download file looking for UBB Message, found place in script giving message "ACCESS DENIED":

$ubbt_lang['NO_PROCEED'] = "UBB Message";
Found in: /languages/english/generic.php

For message "Access Denied":
$ubbt_lang['BAD_GROUP'] = "Access denied.";

NO_PROCEED found in: /libs/html.inc.php
BAD_GROUP found in: number of file locations

Without being able to log in, not sure if I can fix myself.

I have opened a ticket.

if you have FTP axx.. clear out the /cache directory.. del all but index.html

Thank you. Did this and still receiving same error.

Rick is looking at it now
