I have read a post which have a similar problem but was not resolved!
Here are the error I am getting in softaculous :
The following errors were found :
* Could not write the Configuration File **update_pass.php**
* Could not write the Configuration File **admin_configure.php**
* Could not write the Configuration File **includes_configure.php**
for the url : http://grandeurdz.fast-page.org
I left the directory field empty like always.
Nothing else is changed except for some settings like username and all
it always gets stuck at 95% then gives me these errors
The installation package from osCommerce contains over 64,000 thousand files. However, free hosting accounts are limited to 60,000 inodes (which includes both files and directories).
So it looks like osCommerce is just too big to fit on a free hosting account.
I think you may need to choose a different ecommerce suite instead if you want to host a store with us.
