Fail to upload photos and timeout access to PDF forum

[cnleio]

Recent days i met a problem to visit PDF forum ... first i can't upload photos in Leio's PLA military photo thread then it's timeout access to PDF forum, but i have no any problem to upload photos in other threads, except Leio's PLA military photos
