Issue to add my logo on magento 2.5

[clemence_benharbon]

Hello,

I want to change my logo, welcome text... on my website. Everytime I try to do so I get the following message "Something went wrong while saving this configuration: Area is already set".

I uploaded the last version of magento.

Any idea how to fix this bug?

Thanks!

Sharon

Hi @clemence_benharbon

Well , as you mention that when you click on save button its showing something went wrong - so you need to check in var/log directory -  go to your var/log directory found exception.log from there

Open it and past that log over here - so its help us to troubleshoot the issue !

Hi Manthan,

Thank you for your reply, I think this is what you're looking for (I hope so ):

Hi @clemence_benharbon

Looking at your error log - it looks like DOM element is not installed on your server.

apt-get install php-xml
sudo apt-get install php5-dom

if you are using php7 then use below command :

sudo apt-get install php7-dom

Refer below links for more details  :

https://magento.stackexchange.com/questions/105712/magento-2-0-2-installation-fatal-error-domdocumen...

Hope it helps

[clemence_benharbon]

Dear Manthan,

Thanks for the helps. The DOM is now installed and I do not see anymore errors in my files but I still get the same message "Something went wrong while saving this configuration: Area is already set" when I try to change something on the header.

Any idea?

[clemence_benharbon]

Dear Manthan

I have an issue with my logo, I followed normal steps:
1. Magento Admin > Content > Configuration > [store] > Header > Logo Image [Upload]
2. Set Logo Image Width and Height, just fill in numbers, no need to use 'px'.
3. Clear Pearl Theme related cache.

But unfortunately even if I try to change the px the logo always looks big comparing to the page as you can see here: https://poykee.com/

Any idea how to fix this? Which pixel size to use for the logo?

Thanks!

Clemence

I had created custom theme in Magento 2 and I had declared the theme logo in the app/design/frontend/vendor_name/theme_name/layout/default.xml

<?xml version="1.0" encoding="UTF-8"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">

                <argument name="logo_img_width" xsi:type="number">300</argument>
