UBB.threads PHP Forum Software Community Forums UBB.threads Installation and Upgrade Support Upgraded to ver8 - now can't login

I recently upgraded our forum to version 8. The upgrade seemed to go smoothly, but after the upgrade, I am unable to login. I type the username/password, the screen goes to the forum list, but I'm still logged out.

I've double checked permissions, and cleared cookies. Any ideas?

I can browse the forum fine, just can't access anything that requires login.

Is your forum behind a Content Delivery Network such as CloudFlare? If so, have you cleared all of the expired assets from after you've upgraded? What does a hard refresh (Ctrl F5) show after attempting to login? What browser are you using? If Safari they no longer follow web standards, so it is not recommended to depend on it.

No. It's running on a linux box. It was running on a virtual private server, and I wanted to try it in a different environment before asking for help.


Hard refresh has no effect. I've also tried it in private browser windows. I've tried in Firefox and Chrome.

I was logged in as sysop after the upgrade finished The next morning, I couldn't log in.

Interestingly, some of my students who had been logged in before the upgrade, remained logged in after this started happening. No one else could log in.

fwiw, I also tried changing to the default stylesheet, since I was using a custom one. Still couldn't log in.

if I had to guess here, I was thinking that it might be a cookie issue but you mentioned that you attempt a login in private mode and different browsers...

Do you have a copy of the UBB.threads Test Script installed? It should display any potential issues with your hosting environment if it detects any... Are the paths and URLs all set correctly in your includes/config.inc.php file? What do you have set as your cookie prefix?

Just installed it. Here's a screenshot:




Just double checked the paths and URLs. They all look good.
The cookie prefix is: phx

I just updated the Test Script to eliminate a PHP8 strict error when hosts don't allow exec, which should make the test script load fully.

Do you have Let's Encrypt or another free certificate authority on your hosting server? In testing we've found some rare instances where cookies wouldn't be created properly when SSL isn't in use in PHP8.

It turned out to be https. Once I enabled the security certificate, I had to edit my config so it didn't refer to http addresses. (Caused infinite redirect problems after enabling https).

Now I'm able to login, but not able to load pages in admin. They're all outputting blank pages now. Checking permissions now.

At least authentication is working, so that's a relief!

Thanks for all of your help!

Do a hard refresh on the landing for the control panel and see if it loads, there's a cookie issue fixed in v8.0.1 relaxing to strict mode that we've been testing, if it works the fix is to

Edit /forums/admin/doapproveusers.php and remove line 176 where it mentions

A hard refresh didn't solve the problem. I've double checked permissions. All admin pages are coming up as empty white pages. (I also tried the fix, just in case, but no change)

It is not a NGINX server is it?
I have had cache issues with that type server.
Causing settings not to stick
So I exclude ubbthreads.php from the cache in cpanel

Hmmm..no, I'm using apache

It would still be apache as well as a Linux os
NGINX just adds features like site caching proxy etc
check with your host.
Also they usually have a setting in cpanel for NGINX if it is used

I gotcha..I don't believe I'm using NGINX

You need to check

Just checked. I'm not running nginx. I guess the question is now..should I be?

Do your error logs show anything when the page blanks?

I would only use it if the host provides it as part of the hosting plan and then with caution.
It is just a cache on the server and sometimes it causes issues such as make a change in ubb and it appears the change did not complete
