Getting Blank Pages ?

Hi,

I have some difficulties to access ThaiVisa for about 1 week.

I am in Pattaya using a 3BB 8M package and don't have this problem on any other site I visited.

I sometime get an empty/blank page with a curious HTTP/0.9 answer:

http://www.thaivisa.com/forum/forum/1-thai-visas-residency-and-work-permits/

GET /forum/forum/1-thai-visas-residency-and-work-permits/ HTTP/1.1

HTTP/0.9 200 OK

Trying to refresh the page (F5 or Ctrl-F5) does not change anything.

Trying another page of ThaiVisa can sometimes success to display.

Once a ThaiVisa page correctly displayed (with a HTTP/1.1 answer)

I can come back on the one who did not (usually visa forum) and it now works !

No idea where or what... ??
