I am unable to upgrade suitecrm version from 7.8.5 to 7.9.1. Actually when I upload the upgrade package into the upgrade wizard then a notification appears that the package is uploaded now you can continue with the up-gradation but when I hit next button a notification appears to upload the package for installation. I have also tried by changing the file permission but nothing happened.
I request you to help me to solve this issue. Thanks in advance.
I am attaching the error messages.
