[Solved] Exporting from Wordpress: connection lost. How to fix?

hi, I have a locolhost copy of my wp site, but when I export ghost file I get a network connection lost after downloading 3kb. is there something to change to be able to downlaod the file, avoiding splitting content and media?

EDIT: The solution was to edit php.ini of my MAMP installation and increase the following variables (I exagerated a bit maybe, but I was using a local installation):
max_execution_time = 30000
max_input_vars = 12340
max_memory_limit = 2560M
upload_max_filesize =1000M
post_max_size =1000M
