Foreign keys/default values/load data infile

Hello all, I'm trying to build a MySQL based site with Cpanel X and i've having a lot of problems. I used MySQL Workbench to do a schema and couldn't upload the .sql file. On that file was also a constraint to foreign keys and didn't work either. I wasn't abble to discover also why couldn't I use the DEFAULT value in CREATE TABLE query.

Any help on MySQL Workbench vs Cpanel will help.
Here goes the .sql forward engineered file:
