[dhwanil_shah1]

Hello Everyone.

   I  un-commented the ini_set(display_errors,1); in app/bootstrap.php to see the error and following is the output when i try to access the Categories or Products management page from the admin panel.

Fatal error: Uncaught Error: Call to a member function isSwatchAttribute() on null in /var/www/html/magento2/app/code/Magento/Swatches/Helper/Data.php:532 Stack trace: #0

Hi @dhwanil_shah1

Looking at the error - its coming from app/code/magento directory - so just to confirm with you - which magento 2 version are you using ?

Also here - /magento2/app/code/Magento/Swatches/Helper/Data - in this location have you created any custom module or anything ? as error is coming from there only!

Hello @dhwanil_shah1

It seems you made any customization related to Swatches, is it? or it is calling 

file magento2/app/code/Magento/Swatches/Helper/Data.php line @532 

 Please confirm once.

Hi Manthan,

    Thanks for your reply and to answer your first question, I am using version 2.2. Also, no I have not made any changes. I just stopped working after I uploaded Amely theme from ThemeForest.

Hi Manish,

  Thanks for you reply, I have not made any changes or customization in Swatches. I have barely made any changes and most of them are basic URL setting changes and it stopped working after I uploaded the new theme.
