How did I upgrade earosacoustic.com from Magento 2.0.2 to 2.2.2?
(Dmitry Fedyuk) #2

In my case, the design theme contained the following declaration:

<block class="\Magento\Framework\View\Element\Template" name="earos.pdp.after" template="Magento_Catalog::product/view/footer.phtml"/>

I has changed it to:

<block class="Magento\Framework\View\Element\Template" name="earos.pdp.after" template="Magento_Catalog::product/view/footer.phtml"/>

I’m getting this exception,which file to change


(Dmitry Fedyuk) #5

You should set a PHP debugger’s breakpoint to the specified code point, and find out the layout container with an invalid name.
