Not valid template file:adminhtml/base/default/template/foldername/innerfolder/Info.phtml

Question

I am working on a custom module, Grid section is working fine, I want to view the data in my custom tab,

This is my code.

app/code/local/Folder/Modulename/Block/Adminhtml/Adminquote/View/Tabs.php

$this->addTab("form_section", array(
        "label" => Mage::helper("adminquote")->__("Quotation Details"),
        "title" => Mage::helper("adminquote")->__("Quotation Details"),
        "content" => $this->getLayout()->createBlock("adminquote/adminhtml_adminquote_view_tab_info")->toHtml(),
        "active" => true
));

app/code/local/Folder/Modulename/Block/Adminhtml/Adminquote/View/Tab/Info.php

class Folder_Modulename_Block_Adminhtml_Adminquote_View_Tab_Info extends Mage_Adminhtml_Block_Template implements Mage_Adminhtml_Block_Widget_Tab_Interface
{
    protected function _construct()
    {
      parent::_construct();
      $this->setTemplate('adminquote/view/info.phtml');
    }
}

app/design/adminhtml/default/default/layout/adminquote.xml

<adminquote_adminhtml_adminquote_view_tab_info>
<reference name="content">
   <action method="addTab">
      <name>adminhtml_adminquote_view_tab</name>
      <block>adminquote/adminhtml_adminquote_view_tab_info</block>
   </action>
 </reference>

etc/config.xml

<?xml version="1.0"?>
<config>
<modules>
    <Folder_Modulename>
        <version>1.0.1</version>
    </Folder_Modulename>
</modules>
<global>
    <blocks>
        <Folder_Modulename>
            <class>Folder_Modulename_Block</class>
        </Folder_Modulename>
    </blocks>
</global>       
<adminhtml>
   <layout>
        <updates>
            <modulename>
                <file>adminquote.xml</file>
            </modulename>
        </updates>
    </layout>
</adminhtml>
</config>

I am getting error in system.log

2019-01-09T11:52:36+00:00 CRIT (2): Not valid template file:adminhtml/base/default/template/adminquote/view/Info.phtml

Info.phtml file exists in that path.

I don't know why its showing template not valid, Can anyone suggest me to fix this,

Thanks.

There are several things wrong in your layout file

<adminquote_adminhtml_adminquote_view_Tabs_Info>
    <reference name="content">
        <block type="adminquote/adminquote_adminhtml_adminquote_view_Tabs_Info" name="adminquote_adminhtml_adminquote_view_Tabs_Info" />
    </reference>
</adminquote_adminhtml_adminquote_view_Tabs_Info>

The identifier adminquote_adminhtml_adminquote_view_Tabs_Info should correspond to a controller action, or a layout handle. You'd fix that first, according to how your module is implemented

I don't see any admin router defined in your config.xml file, so I suppose you want to inject your custom tab in an existing Magento module. If that's the case, here you have an example about how to do that https://makandracards.com/magento/10947-add-a-tab-to-the-admin-product-screen

Next, your block type is wrong

According to the config.xml you've pasted the block type should be Folder_Modulename/adminhtml_adminquote_view_tabs_info (capital letters are totally relevant, unless you are working under a Windows system... and I hope that's not your case). This applies both for the layout file & the class where you define the block for your tab (app/code/local/Folder/Modulename/Block/Adminhtml/Adminquote/View/Tabs.php)

Once this 2 problems are fixed, the template path loaded by application should be app/design/adminhtml/default/default/template/adminquote/view/Info.phtml (again, capital letters are totally relevant)
