This is blocked by the server (maybe because that page has too many inputs)

Please contact your hosting provider, ask them to check and correct it for you. They should be able to check and solve the issue easily

...please tell me what kind of problem is it on the server side?
We had a dedicated server and I see no problems at the log files.

Hi Michal

I don't have server administrator experience, so I don't know exactly what's causing this. I only know that it's not something from my code

For this, I really need your help to contact your hosting provider (who has server administrator experience) and they will fix it for you. In many cases, it causes by this security addon suhosin.org/ (blocks the request). It could also be a fireware software from the server...

Could you please try to contact them as I said?

Tuan
