Trying to upgrade 7.5 to 7.5.1 gives blank screen

I have two separate instances of SuiteCRM, both at version 7.5. I am trying to upgrade both of them to 7.5.1, but when I click Admin->Upgrade Wizard, I get a blank screen with only the SuiteCRM “tray” displayed on the left side. I’ve rebooted both servers, done QRR and it completed successfully, but the problem persists.

Please help!

Please provide more information…

What is your environment set up?

Did you set the correct permissions pre and post upgrade?

Have you checked your suitecrm.log or upgradeWizard.log?

Have you turned on PHP errors to see if an error is being outputted?

Hi there. Thanks for the reply. My environment is a Ubuntu Linux server, fully updated.

The SuiteCRM system was running perfectly with several upgrades (including 7.5.0, until I tried the Upgrade Wizard).

I am not sure of the permissions pre- and post-upgrade? Where can I find those?

we are facing same problem, is there any solution ?

same for us …

So this is not an isolated incident. Can anyone provide next steps, please?

We have similar issue.
After upgrading from 7.4 to 7.5.1 the Calendar dashlet is blank and frozen.
You have to logout and log back to display it but once you go to any other screen and go back to Home
it is blank and frozen again.

This information would be helpful to know. Can someone point us in the right direction, please?

After having issue with the Calendar dashlet display due to 7.4 to 7.5.1 upgrade
we decided to experiment with 7.4 to 7.5.0 upgrade using the same VM snapshot that was earlier used for 7.5.1 upgrade.
Two attempts to upgrade to 7.5.0 failed - a blank screen appeared once the upgrade started.
It now appears each time we try to load Admin/Upgrade Wizard screen.

I did some poking around.

On my Linux server, I deleted all the files in the /var/www/suitecrm/upload/upgrades/patch folder. I went to the Upgrade Wizard and received this error: “Upload file missing or has been deleted. Refresh the page to go back to UpgradeWizard start”. Once I refreshed the page, it worked successfully and I was able to upgrade my CRM.

I did the same on my Windows server (C:\Bitnami\wampstack\apps\suitecrm\htdocs\upload\upgrades\patch) and it also worked successfully.

Thanks!! I would have never thought to try this.

Did it fix the issue for you? I hope so!

It did not fix the issue of blank Calendar dashlet on Hope screen.
