Dear Melvine Mel,
I installed the quickstart package in localhost, I only set 'display_errors=Off' in PHP.ini file, it worked for me.
If it persist, please try :
Tip 1: Turn off "display errors"
In php.ini, find line "display_errors=On" replace with "display_errors=Off"
Tip 2: Increase execution time in php.ini
Find line "max_execution_time=30" change to "max_execution_time=3000"
Tip 3: Increase memory limit
Increase "memory_limit=128M" to "memory_limit=256M"
Tip4: Find the term "ENGINE=InnoDB" and replace ALL with "ENGINE=MyIsam". It can be changed in /installation/sql/mysql/joomla.sql and in /installation/sql/mysql/sample_data.sql
Thanks
