Magento – Core Javascript files aren’t working, and admin menu’s won’t dropdown

admincoreerrorfrontendjavascript

I have been migrating a Magento install to one server from another. Normally an everyday process – however I have hit a brick wall, and I think I've hit that point where I am too frustrated to see the solution which hopefully is right in front of my eyes…

All my core JavaScript files seem to be giving me problems, on both the front end and the back end. I can't use the Magento admin menu's, because they're managed by the core js files…

Here's the screens of the error messages showing up in firebug.

Backend: http://i.imgur.com/TnYEkSI.png

My first thought was permissions weren't set correctly on the JS folder, but I've reset them 3 times, so it shouldn't be that unless 755 for the folders and 644 for the files is incorrect.

Any help would be greatly appreciated, thanks!

The answer for me turns out to be related to the Magento JS and CSS Minification process.

Prior to the migration I enabled them and disabled them after noticing a few problems with the process. It went back to working order on the live site, however it completely modified the theme's javascript and css files.

Replacing all the RWD theme CSS and Javascript files along with my child theme's CSS and Javascript files resolved the problem.

I wish there was a way to recover the non-modified CSS files but if redoing my CSS file is the worst outcome from all this I am okay with it.

Admin Adminhtml WYSIWYG TinyMCE – How to Edit Admin TinyMCE JavaScript Code Without Modifying Core Files

You can esily create your own module (depends on Mage_Adminhtml) which is extending that js file:

config.xml:

<?xml version="1.0"?>
<config>
    <modules>
        <Your_Module>
            <version>0.0.1</version>
        </Your_Module>
    </modules>

    <adminhtml>
        <layout>
            <updates>
                <your_module>
                    <file>your/module.xml</file>
                </your_module>
            </updates>
        </layout>
    </adminhtml>
</config>

In your layout file you add a custom js to the header:

<?xml version="1.0"?>
<layout>
    <default>
        <reference name="head">
            <action method="addItem">
                <type>skin_js</type>
                <name>your_module/wysiwyg/tiny_mce/setup.js</name>
                <params/>
                <if/>
                <condition>can_load_tiny_mce</condition>
            </action>
        </reference>
    </default>
</layout>

And in the new setup.js you can overwrite the prototype object:

(function (getSettings) {
    tinyMceWysiwygSetup.prototype.getSettings = function (mode) {
        var oSettings = getSettings.call(this, mode);
        oSettings.extended_valid_elements = "article[class]";
        return oSettings;
    };
}(tinyMceWysiwygSetup.prototype.getSettings));

Magento – magento 2 admin url not working and loaded frontend is all messy

First of all, apply proper permissions, enable apache rewrite_module and refresh apache server.

chmod -R 777 /var/www/html/MAGENTO_2_ROOT_DIRECTORY/

sudo a2enmod rewrite

sudo service apache2 restart

For messy frontend, run following command from Magento root:

php bin/magento setup:static-content:deploy

Now clear var directory except .htaccess file and check admin. If you get 404 page, there may be an issue of Symlink. Fot this, Edit apache config file

sudo gedit /etc/apache2/apache2.conf

and replace this code :

<Directory /var/www/>
Options Indexes FollowSymLinks
AllowOverride none
Require all granted

with

<Directory /var/www/>
Options Indexes FollowSymLinks
AllowOverride All
Require all granted

Note: changed AllowOverride none to AllowOverride All

Now restart apache sudo service apache2 restart and check admin. This should fix admin 404 issue.

Also make sure, you don't leave /app/etc/ directory writeable
