Hello, I want to upgrade from version 7.9.8 to newer version but I’ve got a problem.
Navigating to upgrade wizard it’s easy, but there is an error (500 internal server error). There is no error in suitecrm.log file, no error in upgradeWizard.log file besides this:
Mon, 04 Jun 2018 10:35:41 +0200 [UpgradeWizard] - setting session variables…
Mon, 04 Jun 2018 10:35:45 +0200 [UpgradeWizard] - [At end.php]

Can you find your web server log? It’s usually called php_errors.log or errors.log.
What are your versions of OS, Web server, PHP, and database? Thanks
Even in Local environment.
OS version: Windows 10,
Web Server: Apache24,
PHP: PHP 7.0.8,
Zend: Zend Engine v3.0.0,
Database: MySQL.
In my logs it shows this:
[spoiler][Fri Jun 08 08:51:38.879370 2018] [:error] [pid 10832:tid 1940] [client ::1:55630] PHP Fatal error: Cannot declare class Account, because the name is already in use in C:\xampp\htdocs\upgrade\LindexKS\LindexCRM\modules\Accounts\Account.php on line 369, referer: http://localhost:8080/upgrade/LindexKS/LindexCRM/index.php?module=Users&action=index[/spoiler]
Also it displays it on client interface.
You should turn off display_errors in your php.ini, so the errors only show in the logs, not on the screen. That is the recommended setting.
I will continue with this thread on your other post here

we don’t need two threads, now that we are down to one single error 
Yes, you can dissable public write access on this one. Thank you.
