Hello Zahid,
I verified prior to posting my last reply that posts and pages, along with the entire site, work fine with All In One SEO and TubePress installed.
As you can see in this image, I have TubePress and All In One SEO active

As you can see here, the SEO fields are there, meaning All In One SEO is still active, and TubePress is also active.

Unfortunately, this does not appear to be an issue with TubePress as it is working fine in my test environment as well as on multiple live WordPress sites that I have checked.T
Thanks!
