Why "Access denied" in CMP table on MODX REVO?

Question

PHP

Good afternoon!
I created my component based on ModxExtra and installed it.
When you open the component page, the table displays "Access is denied" (in Denver, on the hosting, the inscription "No data for output"), when you try to create records, they are actually created in MySQL, but are not displayed in the plate on the page

Well, I'm answering my own question
1. "Access denied" - an extra character before <?php in the ../assets/components/component_name/connector.php file
2. The data was not displayed due to an error in the .../core file /components/component_name/processors/mgr/item/getlist.php
$isLimit = !empty($_REQUEST['limit']);
$start = $modx->getOption('start',$_REQUEST,0);
$limit = $modx->getOption('limit',$_REQUEST,20);
$sort = $modx->getOption('sort',$_REQUEST,' name ');
$dir = $modx->getOption('dir',$_REQUEST,'ASC');
$isLimit = !empty($_REQUEST['limit']);
$start = $modx->
$limit = $modx->getOption('limit',$_REQUEST,20);
$sort = $modx->getOption('sort',$_REQUEST,' login ');
$dir = $modx->getOption('dir',$_REQUEST,'ASC');
