new posts disappearing

[papa]

Heres the problem. I first open the forum and see all the new posts. We'll say 10 total. I start reading them and then need to go do something so I am away from the computer awhile. I minus the page down , after about 30 min. I come back , bring the page to full size and I only have 4 posts showing now.

 

To see the other posts , I now have to go to the back room , Ill. politics , national politics, etc.....as the case may be, to read them .

 

This isn't the first time this has happened , and it doesn't happen every time . I thought maybe it had been fixed but here it has done it again this morning.

 

Any ideas on this ??? By the way , I have done this since joining this forum and never had an issue till the new updates.
