pages within forum show error (41)

[jwozni2]

I was doing some updates on my general site today and I noticed that when you click on the particular topic in the forum there is no content that comes up. I didn't knowingly make any changes to the forum directory. The forum was set up about 3 months ago and worked great until I noticed this issue now. I checked the config file and everything appears to be fine. This is not an installation issue because I had it working great a couple of days ago. I deleted and restored the database as well and that didn't do anything.

When I click on any page I get a MyBB Error (41)
This is just one example:

Problem url: http://dentalimplant411.com/dental-chat-...um-11.html


Home url: http://dentalimplant411.com/dental-chat-room/

My version is 1.6.12
I was able to upgrade from 1.6.10 to current version without problem.

Thank you in advance for all your assistance.

I even tried to upgrade to the current version. I uploaded the files and I get this message:

Did you remove the 'lock' file from the installer as told?

[jwozni2]

I did and the upgrade was successful. However that did not change the status of all the pages.
Thanks.

If the 'lock' file wasn't created after upgrade, simple create a file called 'lock' in the install directory.
