old bolting new bolting

most of the links in forum connecting to main page why?

Possibly due to forum updates and changes in the background.

We've had many updates since that time.
So, you can use this root part '[COLOR=#000000]https://www.avevaworldforum.com/showthread.php?[/COLOR][COLOR=#000000]'[/COLOR] and add thread number '3770'
If you have:

http://www.pdmsworld.com/forum/showthread.php?t=3770&highlight=bolt

then just combine it

Thanks you very much for your reply

The above link not working and its connecting to main page of the forum
