I keep getting an error when I try to upload large files. 3 - 4 MB
It says, can not move files?

Dear Carrit,

Probably the problem is in your hosting settings. The value for post_max_size and upload_max_filesize in php.ini must be bigger then your file size. You can set them lie this for example:

post_max_size = 200M
upload_max_filesize = 200M
