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.
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.
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.
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.
