title: Laravel Excel - Error Allowed memory size
body: <p>I use <code>Maatwebsite</code> to load excel files. I'm loading fine several documents, until it gives the next error:</p>
  
  <pre><code>PHP Fatal error:  Allowed memory size of 134217728 bytes exhausted (tried to allocate 32 bytes) in /project1/vendor/phpoffice/phpexcel/Classes/PHPExcel/Cell.php on line 582
  </code></pre>
  
  <p>I'm went to <code>config/excel.php</code> and update <code>memoryCacheSize</code> setting to <code>128MB</code>. After do that I run <code>php artisan cache:clear</code> and <code>php artisan config:cache</code>. Try load again and returns me the same error.</p>
  
  <p>How can I solve that?</p>
