Solution:
Check your php error log
and apache error log
. The issue is probably that the script is timing out somewhere in the database creation and load step.
If so try increasing the max_execution_time
in your php.ini. Edit the php,ini using the wampmanager menu system to ensure you are editing the correct file.
Try changing it temporarily to a larger number like
max_execution_time = 240
But change it back to something sensible like 30 or 60 once the install has completed.
