It's been several weeks since I've logged into the ACP on my phpBB forum (https://www.customsoftwareconsult.com/forum/index.php
). When I tried today, I am prompted for my credentials and it appears they are accepted (I get the interstitial page that reads "You have successfully authenticated and will now be redirected to the Administration Control Panel.". But after a second or two, I'm redirected back to the ACP login page.
I've tried clearing my local cookies but it did not help.
I've tried using the STK tool (customsoftwareconsult.com/forum/stk/index.php). It accepts my credentials and I get the "You have been successfully logged in", but immediately returns back to the login page. I've tried the "generate a new password file" routine (and uploaded the 'passwd.php' to the STK folder), but the password I'm given is not accepted.
Can anyone help?
ETA: I am currently running phpBB v3.0.x (cannot determine the exact version because I can't get into the ACP)
