Cannot Edit Product after upgrade at 1.9.3.2

[digitalenetwork]

I have upgrade my magento from 1.9.2.4 to 1.9.3.2. First this it's all ok.

Now, when i want edit a product, in admin area, the page result dont' load all. 

No errors are quoted as system.log and no errors in exception.log.
I configured the debugging .htacces and added "ini_set ('display_errors', 1);" in index.php

It is highlighted the following error:
Method "core_block_abstract_to_html_after" is not defined in "VES_Core_Model_Observer"

Can someone help me?
Thank you

I see this when i click edit in list productlist logo print error from debug

The real error is write in log of server:

[Tue Mar 21 10:31:29 2017] [error] [client 93.47.45.101] PHP Fatal error:  Undefined class constant 'XML_NODE_PRODUCT_MAX_DIMENSION' in /home/nauticap/web/nauticaportoverde.com/public_html/app/design/adminhtml/default/default/template/catalog/product/helper/gallery.phtml on line 111, referer: https://www.nauticaportoverde.com/index.php/admin/catalog_product/index/key/7f13fefb0f101402e60172d3...

to correct the error, rename /app/code/local/Mage/Catalog/Helper/Image.php  in Image.php.back and resolve it.

Cannot Edit Product after upgrade at 1.9.3.2

Just to clarify - I renamed the image.php file to image.php.bak (located in local app/code/local/Mage/Catalog/Helper) and this then reverted back to the core file (app/code/Mage/Catalog/Helper) this solved the issue. OR like the solution above, copy the file from core and move it to Local.
