After updating wordpress to the last version, I can still see the views to filter my custom posts (and I see the result list) but when I click on the post title to see the post details I got nothing.
Even if I try to change or create a new template, nothing changes.
It may be related to the theme I'm using: Impreza from Up Studio (even if I didn't updated nor modified anything about the theme, just updated WP).
If so, how can I check and manage theme compatibility in order to solve the problem (obviously the client is hurrying...).
thanks a lot

Hi, this is definitely not normal. Can you check a few things for me?
- - Please temporarily disable any non-Toolset plugins and activate a default theme like Twenty Seventeen. Is the problem resolved?
- Please regenerate your site's permalinks. Go to Settings > Permalinks and click "Save"
- Please enable server logging to see if any server-side errors are being generated. You can see how to enable debug logging here:
https://toolset.com/documentation/user-guides/debugging-toolset/

Go in your wp-config.php file and look for define(‘WP_DEBUG’, false);. Change it to:

define('WP_DEBUG', true);

Then add these lines, just before it says 'stop editing here':

ini_set('log_errors',TRUE);
ini_set('error_reporting', E_ALL);
ini_set('error_log', dirname(__FILE__) . '/error_log.txt');
ini_set('display_errors', 'Off');

Then refresh the page on a post that is not showing up. If any server-side errors are thrown, this will create an error_log.txt file in your site's root directory. Please send me its contents. Once that is done, you can revert the updates you made to wp-config.php.
