[xwiki-users] limit of around 10Mb for attached files

I'm trying to Import a backup of around 45 MB in a test environment of Xwiki It fails after clicking UPLOAD;I'm getting a message: XWiki has a default limit of around 10Mb for attached files. This limit can be changed using the upload_maxsize parameter. Check the FAQ for more information. I'm running XWiki Enterprise 2.4.2.31315 on mySQL 5.1 I've changed my.cnf of mySQL to increase max_allowed_packet # The MySQL server [mysqld] port = 3306 socket = /tmp/mysql.sock skip-locking key_buffer_size = 16M max_allowed_packet = 64M table_open_cache = 64 sort_buffer_size = 512K net_buffer_length = 8K read_buffer_size = 256K read_rnd_buffer_size = 512K myisam_sort_buffer_size = 8M This shows in when i run mysqld --verbose --help as: max_allowed_packet 67108864 I've also used the class editor in xwiki to edit the parameter of the preferences Name: upload_maxsize (default) Pretty Name: Maximum Upload Size (default) Validation Regular Expression: (default) Validation Message: (default) Number Type: long (default) Size of the corresponding form element in edit mode : 200000000 (changed) any suggestions?
