Magento fix: while trying to access connect Fatal error: Class Exception not found in Frontend.php on line 90

Essentially you need to edit the level of error reporting to supress php from throwing this error.

so..

index.php

change

error_reporting(E_ALL | E_STRICT);

 error_reporting(E_ALL & E_STRICT & ~E_DEPRECATED);

lib/Varien/Pear.php

error_reporting(E_ALL & ~E_NOTICE);

error_reporting(E_ALL & ~E_NOTICE & ~E_DEPRECATED);

4> downloader/Maged/Pear.php

error_reporting(E_ALL & ~E_NOTICE);

error_reporting(E_ALL & ~E_NOTICE & ~E_DEPRECATED);

Fatal error: Undefined class constant ‘COUPON_TYPE_NO_COUPON’ in mysql4-upgrade-1.4.0.0.1-1.4.0.0.2.php

if you are seeing

Fatal error: Undefined class constant ‘COUPON_TYPE_NO_COUPON’ in /var/www/html/app/code/core/Mage/SalesRule/sql/salesrule_setup/mysql4-upgrade-1.4.0.0.1-1.4.0.0.2.php

edit

/var/www/html/app/code/core/Mage/SalesRule/sql/salesrule_setup/mysql4-upgrade-1.4.0.0.1-1.4.0.0.2.php

change

'smallint unsigned NOT NULL DEFAULT "' . Mage_SalesRule_Model_Rule::COUPON_TYPE_NO_COUPON . '"'

'smallint unsigned NOT NULL DEFAULT "' . 1 . '"'

and

coupon_type = '" . Mage_SalesRule_Model_Rule::COUPON_TYPE_SPECIFIC . "';

coupon_type = '" . 2 . "';

run the upgrade then change the code back agian… real pain!!

Magento tip : Fatal error: Class ‘xxxxx’ not found in pathto/httpdocs/app/ Mage.php on line 520

We have seen this problem listed on just about every magento forum and blog.. Then we hit the error on one of our stores.

Essentially, you install a new module either from command line or Connect and immediately the site starts to throw this error either in backend or front or both.

The simple answer is to turn off compilation.. then install your module and re-run compilation.

Very annoying…

Magento error: Invalid method Mage_Catalog_Block_Product_List_Toolbar::isLastPage

admin — Tue, 28 Sep 2010 15:08:18 +0000

This is an interesting bug that seems to affect some custom templates that have not been fully adapted to 4.1x. This causes some categories with a set number of products to throw the following error:

Invalid method Mage_Catalog_Block_Product_List_Toolbar::isLastPage(Array
(
)
)

Trace:
#0 [internal function]: Varien_Object->__call(\'isLastPage\', Array)

To Fix

Copy this

public function isLastPage()
    {
        return $this->getCollection()->getCurPage() >= $this->getLastPageNum();
    }

and paste in app/code/core/Mage/Core/Block/Template.php after this:

public function getCacheKeyInfo()
    {
        return array(
            'BLOCK_TPL',
            Mage::app()->getStore()->getCode(),
            $this->getTemplateFile(),
            'template' => $this->getTemplate()
        );
    }

To avoid having it get overwritten during next update create the following folders:

app/code/local/Mage/Core/Block/

and add your new Template.php in there.

Fix Invalid Category error in Magento.

admin — Thu, 21 Jan 2010 11:46:37 +0000

This is a trick error with very little information floating around on it. There are various reasons why it happens but essentially something has caused your default store view to forget what the default category is.

magento may throw up a

Mage::throwException(’Invalid categor…’)

error in the diagnostic info.

The fix is easy. Log into admin which will still be working and under configure select manage shops and click on your shop name. Your root category will be empty .. simply select the correct root category.
