Error KCFinder 2.51 - uploading works in 50% ? o.0

Dear MODx Evolution users,

Plz help me.. im using MODx Evolution for a while since Evo 1.0.4 i think.
Yesterday i need to upload some new images with "build-in" KCFinder 2.51 and i have strange error: 400 bad request

I'm so confused, I checked all files, and all having more then 180 kb can be uploaded.

But all having lower then 180 kb shows me error: 400 bad request. Of course i check 5 other installation of MODx Evolution 1.0.15 and all having the same problem :/

What is that.. how can i fix them?

No one can help me ? o.0

Do you have open_basedir in effect? mod_security?

Can you tell us more about your hosting environment in general? Who are you using, what version of PHP, etc?

Hey, im using home.pl hosting and uploading with KCEfinder in MODx Evolution 1.0.14 works god, but 1.0.15 can uploads only images bigger then 180 kb... All images lower then 180 kb uploaded in KCEfinder will show me error message "404 bad request".

If u wanna help me i can send u via pm message with login to MODx Evolution as root admin. [ed. note: haki2015 last edited this post 9 years ago.]

Well i have information from my provider, they upgrade php interpreter from 5.3.27 to 5.3.29 :/
Here is my phpinfo: http://www.ev.soulandmind.pl/phpinfo.php

Do you know if they have mod_security installed? That can cause the problems as well.
