Well since on your screenshots you have max file size set to 128 I can only assume that you edited the correct php.ini file.
I am also quite sure that you didn’t change some random lines there, so it’s interesting error ‘file is too big’ is quite common but ‘file is too small’…well not so much.
Could you please double check that all the correct lines in php.ini are changed as described here: How do I upload files bigger than 2MB / How can I increase the upload file size limit?
and restart your server again after that.
