How to solve this PHP fatal error after installing module? PHP Fatal error:  Cannot redeclare _field_info_field_cache()
  (previously declared in
  C:\xxxx\wwwroot\xxxxx\modules\field\field.info.inc:16) in
  C:\xxxxx\wwwroot\xxxxxxx\sites\all\modules\easy_booking-7.x-2.4\modules\field\field.info.inc
  on line 32


So I got this error notification after turning on Error debug in my IIS Server because previously it only showed a 500 page error.

It seems it's calling two times the same function? Anyone can help?

Edit: I guess it's better I just delete the module but then I get a require_once error:


  PHP Fatal error:  require_once(): Failed opening required '
Put the module back. Check its code. Delete the problematic function named in the corresponding error message from it. Go to admin page. Uninstall the module.

Try to reinstall the module in a proper location. Don't name the folder easy_booking-7.x-2.4. Simply name it easy_booking. If the error still occurs, file a bug at https://www.drupal.org/project/issues/easy_booking?status=All&amp;categories=All
