Memory exhausted

[musicmaster]

In my php_error_log file I have the following error:

PHP Fatal error:  Allowed memory size of 134217728 bytes exhausted (tried to allocate 69 bytes) in C:\xampp\htdocs\_natura\classes\Tools.php on line 979

This is Prestashop 1.6.1.0 and that line is part of following function:

public static function displayError($string = 'Fatal error', $htmlentities = true, Context $context = null)
{
	global $_ERRORS;

	if (is_null($context))
		$context = Context::getContext();

	@include_once(_PS_TRANSLATIONS_DIR_.$context->language->iso_code.'/errors.php');

	if (defined('_PS_MODE_DEV_') && _PS_MODE_DEV_ && $string == 'Fatal error')
		return ('<pre>'.print_r(debug_backtrace(), true).'</pre>');
	if (!is_array($_ERRORS))
		return $htmlentities ? Tools::htmlentitiesUTF8($string) : $string;
	$key = md5(str_replace('\'', '\\\'', $string));
	$str = (isset($_ERRORS) && is_array($_ERRORS) && array_key_exists($key, $_ERRORS)) ? $_ERRORS[$key] : $string;
	return $htmlentities ? Tools::htmlentitiesUTF8(stripslashes($str)) : $str;
}

Line 978 is "if (!is_array($_ERRORS))".

 

I am puzzled what to make of this error. I am working on a 8GB computer and this is just the login screen so I wouldn't expect memory problems. Neither do I understand how an is_array command can cause a memory problem.

 

Can anyone enlighten me?
