How to increase upload max size

Hello, I have an issue with a recent install on Centos 7.

Leantime is working fine but the upload file size seems to be stuck on 5MB. So all files larger than 5MB do not get uploaded.

I have all php.ini settings in place
file_uploads = On
memory_limit = 256M
upload_max_filesize = 64M
post_max_size = 64M
max_execution_time = 300
max_input_time = 300
max_file_uploads = 100

and have also fiddled with max_size inside class.fileupload.php but without success.

Any ideas please?

Additionally kindly advise if there is a way to upload multiple files at once.

Thanks for your effort
