Magento 2.3.4 product shows a blank page after migration process

[radiantweb]

After migrating from Magento 1.9.3 to Magento 2.3.4 I can see a blank product page.

For the solution, after checking that when product is saved from admin side I am then able to see product page and visible.

Another one I can see that ,

1 exception(s): Exception #0 (Magento\Framework\Config\Dom\ValidationException): Element 'reference': This element is not expected.

Is this any layout issue occurs this problem or image issue is making this error ?

Hi @radiantweb ,

This issue is related to the layout XML file. In layout XML you have used reference tag which is not acceptable in magento 2.

Please check below link:

Thanks!

Hello Nishu Jindal, 

From Provided link i have first searched in files in magento directory but in files I could not find with word <reference. 

Then I started finding same word in database then I found much records with reference text in database table catalog_product_entity_text with layout update xml having this code. 

I removed from my local machine but nothing happen.

Hi @radiantweb ,

Please flush magento cache and check.

php bin/magento cache:flush

If you still face issue, then try reindexing using below command

php bin/magento indexer:reindex

php bin/magento cache:flush

Please let me know if we still face issue.

Thanks!

Hello Nishu Jindal,

Thank you for reply again. 

I have checked running bin/magento cache:flush command after deleting database entries but nothing happen.

For indexing If i will run bin/magento indexer:reindex command it will run about 72 hours to complete the indexing process. 

So is there something that i am missing ?

Also to be noticed, on accessing blank product page I am getting some Broken Reference errors too from system.log.

Hi @radiantweb ,

if your reindexing is taking much time. can you please try running reindex for 

catalog_product_attribute only. 

Thanks!

Hi @radiantweb,

You could use this command in order to show what is the issue that you're facing. 

php bin/magento deploy:mode:set developer

However, I think that you have some attributes in table eav_attribute that don't have the right frontend_input. 

Hope it helps! Let me know if you need further assistance.

Hi Ross,

As you stated for eav_attribute frontend_input is not right if this would possible then after saving of product also could not show product on frontend.

Thank you Nishu for your link,

Finally this is solved. I checked for the attribute for page_layout and made it NULL by running mysql query for that perticular product attribute. Then checked for the product page and running.

Now the issue is different images I have copied from Magento 1.9 to Magento 2.0 in pub/media folder not shown in product view page. I can see images in category list page. Can you suggest a better solution for that. 

I have checked that catalog_product_entity_media_gallery_value_to_entity is missing entity id. How to overcome this issue ? Please suggest.
