    ROOT/vendor/cakephp/cakephp/src/Collection/Collection.php, line 37    <h3>Could this be caused by using Auto-Tables?</h3>
<p>
Some of the Table objects in your application were created by instantiating "<strong>Cake\ORM\Table</strong>"
instead of any other specific subclass.
</p>
<p>This could be the cause for this exception. Auto-Tables are created for you under the following circumstances:</p>
<ul>
    <li>The class for the specified table does not exist.</li>
    <li>The Table was created with a typo: <strong><em>$this->getTableLocator()->get('Articles');</em></strong></li>
    <li>The class file has a typo in the name or incorrect namespace: <strong><em>class Articles extends Table</em></strong></li>
    <li>The file containing the class has a typo or incorrect casing: <strong><em>Articles.php</em></strong></li>
    <li>The Table was used using associations but the association has a typo: <strong><em>$this->belongsTo('Articles')</em></strong></li>
    <li>The table class resides in a Plugin but <strong><em>no plugin notation</em></strong> was used in the association definition.</li>
</ul>
<br/>
<p>Please try correcting the issue for the following table aliases:</p>
<ul>
    <li><strong>UsersBadges</strong></li>
</ul>

    ROOT/vendor/cakephp/cakephp/src/Collection/Collection.php, line 37    <h3>Could this be caused by using Auto-Tables?</h3>
<p>
Some of the Table objects in your application were created by instantiating "<strong>Cake\ORM\Table</strong>"
instead of any other specific subclass.
</p>
<p>This could be the cause for this exception. Auto-Tables are created for you under the following circumstances:</p>
<ul>
    <li>The class for the specified table does not exist.</li>
    <li>The Table was created with a typo: <strong><em>$this->getTableLocator()->get('Articles');</em></strong></li>
    <li>The class file has a typo in the name or incorrect namespace: <strong><em>class Articles extends Table</em></strong></li>
    <li>The file containing the class has a typo or incorrect casing: <strong><em>Articles.php</em></strong></li>
    <li>The Table was used using associations but the association has a typo: <strong><em>$this->belongsTo('Articles')</em></strong></li>
    <li>The table class resides in a Plugin but <strong><em>no plugin notation</em></strong> was used in the association definition.</li>
</ul>
<br/>
<p>Please try correcting the issue for the following table aliases:</p>
<ul>
    <li><strong>UsersBadges</strong></li>
</ul>

    ROOT/vendor/cakephp/cakephp/src/Collection/Collection.php, line 37    <h3>Could this be caused by using Auto-Tables?</h3>
<p>
Some of the Table objects in your application were created by instantiating "<strong>Cake\ORM\Table</strong>"
instead of any other specific subclass.
</p>
<p>This could be the cause for this exception. Auto-Tables are created for you under the following circumstances:</p>
<ul>
    <li>The class for the specified table does not exist.</li>
    <li>The Table was created with a typo: <strong><em>$this->getTableLocator()->get('Articles');</em></strong></li>
    <li>The class file has a typo in the name or incorrect namespace: <strong><em>class Articles extends Table</em></strong></li>
    <li>The file containing the class has a typo or incorrect casing: <strong><em>Articles.php</em></strong></li>
    <li>The Table was used using associations but the association has a typo: <strong><em>$this->belongsTo('Articles')</em></strong></li>
    <li>The table class resides in a Plugin but <strong><em>no plugin notation</em></strong> was used in the association definition.</li>
</ul>
<br/>
<p>Please try correcting the issue for the following table aliases:</p>
<ul>
    <li><strong>UsersBadges</strong></li>
</ul>

Could this be caused by using Auto-Tables?

Some of the Table objects in your application were created by instantiating "Cake\ORM\Table" instead of any other specific subclass.

This could be the cause for this exception. Auto-Tables are created for you under the following circumstances:

The class for the specified table does not exist.
The Table was created with a typo: $this->getTableLocator()->get('Articles');
The class file has a typo in the name or incorrect namespace: class Articles extends Table
The file containing the class has a typo or incorrect casing: Articles.php
The Table was used using associations but the association has a typo: $this->belongsTo('Articles')
The table class resides in a Plugin but no plugin notation was used in the association definition.

Please try correcting the issue for the following table aliases:
