During our PrestaShop 1.5 testing, we came upon the following error when attempting to install PrestaShop 1.5:

An error occurred during installation

In this file, install/error_log, we found the following error:

[14-May-2012 13:54:30] PHP Warning:  simplexml_load_string() [<a href='function.simplexml-load-string'>function.simplexml-load-string</a>]: Entity: line 1: parser error : Space required after the Public Identifier in /home/userna5/ on line 41

Therefore, we reviewed this file - classes/LocalizationPack.php - and saw the problem was with the $file variable being passed here:

public function loadLocalisationPack($file, $selection, $install_mode = false)
if (!$xml = simplexml_load_string($file))
return false;

During our troubleshooting we emailed ourselves the $file variable (using the php mail function) and found out the problem was in this file - install/models/install.php - at line 401:

$localization_file_content = @Tools::file_get_contents(''.$version.'/'.$data['shop_country'].'.xml');

What was happening is that $localization_file_content was set to, however that file did not exist. At the time of this writing, that URL was resulting in a 404 error. To resolve this issue, we added the following line in install/models/install.php:

$localization_file_content = @Tools::file_get_contents(''.$version.'/'.$data['shop_country'].'.xml');

The unset function deleted the variable, and therefore ran the following code, which creates the contents based upon files already stored within PrestaShop 1.5 (instead of trying to download them from - which is resulting in a 404 error)

if (!$localization_file_content)
$localization_file = _PS_ROOT_DIR_.'/localization/default.xml';
if (file_exists(_PS_ROOT_DIR_.'/localization/'.$data['shop_country'].'.xml'))
$localization_file = _PS_ROOT_DIR_.'/localization/'.$data['shop_country'].'.xml';
$localization_file_content = file_get_contents($localization_file);

Hello Sunil,

Have you tried going back to the previous step and then retrying? Does it do the same? Are there any other issues with the install? Error messages? Have you tried this on a completely clean folder structure or are you trying to overwrite some files? Which specific version are you trying to install?

Kindest Regards,
Scott M
