Too big POST data. Reduce the data or increase the "post_max_size"

Question

I'm trying to upload a gzipped Mysql backup (71,2mb) through Adminer and it throws me this error:

Too big POST data. Reduce the data or increase the "post_max_size" configuration directive.

Even though my post_max_size and other php.ini settings is like this:

post_max_size = 1024M
upload_max_filesize = 1024M

Why do i keep getting this error?

Don't only check values in php.ini, as they can be overwritten by a .htaccess file or in PHP code. Run a phpinfo() and compare values in left & right column. The values in the right column are those actually in use.

Also take the notes from the documentation into account:

Sets max size of post data allowed. This setting also affects file upload. To upload large files, this value must be larger than upload_max_filesize. If memory limit is enabled by your configure script, memory_limit also affects file uploading. Generally speaking, memory_limit should be larger than post_max_size.

So, you might also need to change memory_limit:

memory_limit > post_max_size > upload_max_filesize

Don't forget to restart your servers if you are working locally.. ;) — mmsarquis, Mar 21 '19 at 19:26
