[godilite]

Please can someone help me, I have installed this extension on magneto 2.3.x, everything works fine except that the seller can't find a form to post products, the manage product page on the seller dashboard shows the title Account and nothing else except a white page. Please I really need help from everyone

I have tried to install Apptha on Magento 2.3 but failed.... in my experience, it's perfectly working with PHP 7.1 and Magento 2.2. before you work with Apptha check file permissions. I have used this without any errors (01-02-2020)
