Magento2 Something went wrong while saving the page

Question

I have problem with creating new page from backend it shows me this message: Something went wrong while saving the page.

I can edit and save the page but I can't create the new page. any idea??

Answer 1

Yes I got the solution for that:

I have installed MageWorx SeoBase extension that extension adds two fields in the cms_page table: 1. meta_robots and 2. mageworx_hreflang_identifier

but that field does not show on the content > page and both fields are set as nullable = false;

that's why the page was not saving I just go the database, open the cms_page table and just select true in a null field and now its working.

Answer 2

The best idea to get the solution is try and catch which was introduced in PHP 5 then you only need to check exception message.

try{
  //Your code logic
}
catch (\Exception $e) {
  //First find the message and then echo $e message.
  echo $e->getMessage(); die('errorMessage'); 
  $this->messageManager->addException($e, __('Something went wrong while saving the page.'));
}
