Responsive File Manager Memory Limit Error - php

Question

i am having trouble uploading large files with Responsive File Manager, it shows Not enough memory limit error.
i tried changing limits in php.ini
upload limit to 100MB
post max size to 100MB
script memory limit to 300MB
max execution time to 300
i also changed the limit in config.php
'MaxSizeUpload' => 100
But still the same error.
now even few 100 kb is not uploading.
what may be the problem?
Edit 1:
i use the default upload.php from responsive file manager for uploading my files
at line 157 the memory error is checked
default upload.php
my config.php

If you are using NGINX you should check configured maximum post entity size. In my default configuration it was less than PHP post file limit.
