Might be a post count issue. I also run into an issue with chrome where I open a resource and I am no longer logged in. if I want to look at that section of the forum I use edge and it works like it's supposed to.
If you could be a little more specific about what is not working for you I can check. There are no blocks on what you can read or view. It is not based on post count. If the problem is lost pictures (seeing just a red X instead of a picture) - that is because the picture was never actually loaded to the forum, it was on a 3rd party hosting platform that no longer exists. That type of picture is lost for good.
An example: Interior Tech Articles - Dash Pad Removal when I tried to retrieve the article, "You do not have permission to view the full content of this resource" was the response.
What happens if you follow this link - can you see the article now ? Dash Pad Removal | Maverick/Comet Forums .
That is what I get, it has to do with cookies or some other setting in chrome for me. Like I mentioned earlier, I use edge for this and it doesn't ask me to sign in again to see the content.
I agree with this - that it has something to do with your browser settings. There are no blocks on the forum end of things .............
I could probably take the time to fix it but I hate trying to figure it out when there's a simple work around!
