<?php foreach ($panelsRecords as $record){ ?>

<?php include("_panelContent.php") ?>

<?php } ?>

For Option 2, you're using a semi-colon which terminates the loop right away. The equivalent to this is:

    <?php foreach ($panelsRecords as $record){ } include("_panelContent.php"); ?>

// Define toolbar buttons. See list of toolbar buttons here: https://www.tinymce.com/docs/advanced/editor-control-identifiers/#toolbarcontrols

toolbar3: "styleselect",

You have the "styleselect" button in toolbar1 and toolbar3. If you remove it from toolbar3, it would show up only once.

$query = @$_REQUEST['query']; // this will hold the keyword

  // load records from 'homepage_insets'
  list($homepage_insetsRecords, $homepage_insetsMetaData) = getRecords(array(
    'tableName'   => 'homepage_insets',
    'perPage'     => '10',
    'loadUploads' => true,
    'allowSearch' => true,
    'where'       => " title LIKE '%".mysql_escape($query)."%' OR content LIKE '%".mysql_escape($query)."%' ",
  ));

$query = @$_REQUEST['query']; // this will hold the keyword

  // load records from 'homepage_insets'
  list($homepage_insetsRecords, $homepage_insetsMetaData) = getRecords(array(
    'tableName'   => 'homepage_insets',
    'perPage'     => '10',
    'loadUploads' => true,
    'allowSearch' => true,
    'where'       => " title_keyword LIKE '%".mysql_escape($query)."%' OR content_keyword LIKE '%".mysql_escape($query)."%' ",
  ));

and you can add all the fields you want to search using that format.

<form action="search.php" method="post">
    <div class="row no-gutters mt-3">
        <div class="col">
            <input type="text" name="query">
            <input type="submit" name="submit" value="Search">
        </div>
    </div>
</form>

After that, on search.php I would change this:

  // load records from 'homepage_insets'
  list($homepage_insetsRecords, $homepage_insetsMetaData) = getRecords(array(
    'tableName'   => 'homepage_insets',
    'perPage'     => '10',
    'loadUploads' => true,
    'allowSearch' => true,
  ));

to something similar:

$query = @$_REQUEST['query']; // this will hold the keyword

  // load records from 'homepage_insets'
  list($homepage_insetsRecords, $homepage_insetsMetaData) = getRecords(array(
    'tableName'   => 'homepage_insets',
    'perPage'     => '10',
    'loadUploads' => true,
    'allowSearch' => true,
    'where'       => " title_keyword LIKE '%".mysql_escape($query)."%' ",
  ));

Let me know if that works.

If that did fix the error, your host has to adjust some server settings so it doesn't block your scripts.
