Blank screen after System Check in Upgrade Wizard

I am trying to upgrade from 7.9.0 to 7.9.7 using the Upgrade Wizard but as soon as I click Next, it checks the system, then goes to a blank workplace. The menus are still showing at the top.

I would appreciate your guys help.

I would recommend that you enable PHP errors within SuiteCRM and/or check your PHP error log files. I would also recommend you check your suitecrm.log file for any errors. If you receive a blank page, generally something is failing to load because of an error within the application, such as a bug in the PHP code.There are hundreds of posts on the forum detailing how to do this, most likely summarising better than I will here, so please search the forums for the wealth of knowledge.

It turned out that some folder or file didn’t have correct permissions. I ended up just re-doing the chmod command for the html folder and all that’s in it. That fixed the issue.

Also as soon as I got through to upload an upgrade zip file, I chose the file and it showed a message that the max upload limit is too small.
All of my limits were set correctly in php.ini file. But it turned out switching to a different language and then back to english like they did in another thread resolved the issue.

I think this is something that maybe should get attention so that the issue can be fixed and people wouldn’t have to play with languages and stuff like that. Also for the permissions issue, maybe add a requirement or something before installing the SuiteCRM so that all of the permissions would be done before installing the crm so one wouldn’t have to deal with permissions problem when he wants to upgrade. Because at the time I was installing the Suitecrm I passed all of the permissions requirements, yet i still had problems with permissions at the time of upgrade.
