How to increase the attachment upload size?
The upload attachment file size in Zurmo is determined by your server’s PHP and mysql settings.
Two settings can be modified in the php.ini file:
‘post_max_size’ is the limit for all the content of your post, while ‘upload_max_filesize’ is specific to a single attachment size. Many people choose ‘post_max_size’ to be a multiple of ‘upload_max_filesize’ to allow multiple files to be uploaded, but this is not essential.
The third setting is set in mysql .ini or .cnf file(depends on the setup you have):
‘max_allowed_packet’ is the maximum size of one packet or any generated/intermediate string. You will need to restart mysql if you make a change to this file.
Zurmo limits the max upload size of a single attachment to be the smallest value of the three settings listed above.
