Error with config.xml

[Isa_314]

Hello all,

 

I use prestashop 1.3

 

I got an error when listing modules in the Bach Office:

 

Warning: simplexml_load_file(): supplied argument is not a valid Stream-Context resource in /var/www/vhosts/arianpars.com/httpdocs/gourmet/classes/Module.php on line 514

 

What annoys me is that It happens sometimes, not allways

 

I thought that the reason was the properties of the file config.xml and changed them. After some days working , yesterday showed the same error.

 

Here is the code and the place of the error in red

 

foreach ($modules_dir AS $module)

{

$configFile = _PS_MODULE_DIR_.$module.'/config.xml';

$xml_exist = file_exists($configFile);

if ($xml_exist)

$needNewConfigFile = (filemtime($configFile) < filemtime(_PS_MODULE_DIR_.$module.'/'.$module.'.php'));

else

$needNewConfigFile = true;

if ($useConfig AND $xml_exist)

{

libxml_use_internal_errors(true);

$xml_module = simplexml_load_file($configFile);

foreach (libxml_get_errors() as $error)

$errors[] = '['.$module.'] '.Tools::displayError('Error found in config file:').' '.htmlentities($error->message);

libxml_clear_errors();

 

Does anybody know what is happening and how to settle it?

 

Thanks in advance
