Error! No PNG create support?

Can you help me? I don't know about this error.

Tungmaster, Please , image error (Screenshot)

perhaps this error occurs because of hosting. please show us the screenshot.

this error when i upload a picture file (png, gif, jpg, jpeg) to avatar or photo or album. I can't upload a picture file. And i can't select avatar in list. I was set 777 to folders. I use a vps linux KMV

File

Problem in gd library. Наверно

@nursaulet: i can't upload to my avatar and my photo in profile. I think problem in my hosting or code

No, code of the CMS is OK, the problem is in the hosting. Ask hoster to install additional libraries

I aked supporter and he say: hosting no problem. he say i need check my code but i don't edit this code folder

It seems to me that the problem is in the file class.upload.php (incfiles/lib/) Try to reinstall it or try to install latest version.
