Magento 2 - Error when uploading image

Question

I'm trying to change the logo of my Magento store so I go to Content > Design > Configuration, I click Edit on the Default Store View, I scroll down to Other Settings and open Header... I already have a logo there so I click on the trash icon to remove it, then I click on Upload and select the new logo I want from my computer. The logo loads properly, but when I click on Save Configuration, I get the following error message:

"Something is wrong with the file upload settings."

enter image description here

Also I remove the Favicon Icon and I was able to save the configurations with no error, but the icon still appears in the front end even though the Admin shows that there is no icon.

Note: My Magento 2 version is 2.4.4

• Amit Dwivedi: Which version you have of Magento 2 ?
• Abi: Magento 2 version 2.4.4
• Amit Dwivedi: /pub/media/logo/stores/ check for the proper permission

Answer 1

You face this issue because your file is not allowed. Allowed extensions for logo files are jpg, jpeg, gif, and png.

• Abi: my logo extension is png, so that's not the issue
• Tu Van: Make sure your logo extension is lowercase. Eg: if the logo file is mylogo.PNG, magento will throw the error.

Answer 2

Just experienced the same. In my case it was because the file extension was UPPER CASE. Renaming .JPG to .jpg worked a treat for me at least.

I can't quite believe that was the simple answer, but worked in my case. Crazily poor error message if that was the reason!

Answer 3

Go to file vendor\magento\framework\Image\Adapter\Gd2.php

Change function 'validateURLScheme' with the below code:

private function validateURLScheme(string $filename) : bool
 {
 $allowed_schemes = ['ftp', 'ftps', 'http', 'https'];
 $url = parse_url($filename);
 if ($url && isset($url['scheme']) && !in_array($url['scheme'], $allowed_schemes) && !file_exists($filename)) {
 return false;
 }
 return true;
 }
