after installing Language pack (Dutch), icons missing and menus not pulling.

[GoodLook]

after installing a language pack with install wizard: Icons on backend are missing and menus are not pulling? I use magento 2.2.6.

This was a fresh install from yesterday. Only added 1 extension.

My solution found:

goto your ftp site and look for the file in your root magenta folder: /app/etc/di.xml

edit this file, look for "MaterializationStrategy"

<virtualType name="developerMaterialization" type="Magento\Framework\App\View\Asset\MaterializationStrategy\Factory">
        <arguments>
            <argument name="strategiesList" xsi:type="array">
                <item name="view_preprocessed" xsi:type="object">Magento\Framework\App\View\Asset\MaterializationStrategy\Synlink</item>
                <item name="default" xsi:type="object">Magento\Framework\App\View\Asset\MaterializationStrategy\Copy</item>
            </argument>
        </arguments>
    </virtualType>

and change the word "Synlink" to "Copy"

MaterializationStrategy\Synlink

to

MaterializationStrategy\Copy

After this

goto your root directory of magento end find the folder  /pub/static

there you delete the file inside this folder "_requirejs"

And delete or rename the folder inside this folder "adminhtml"
I renamed this folder to adminhtml_old

DO NOT DELETE ANY OTHER FILES

then go back to your page and refresh the view.

This worked for me.
