I have upgrade SuiteCRM 7.11.4 running on my server and I am trying to upgrade to 7.11.15 but this fails
Every time I am trying to upgrade on last step I don’t know why this is happening but
If so, After the upgrade fails, do you see any error messages in any of the:
Suitecrm.log, upgradeWizard.log or your php/apache logs?
It would also be worth ensuring that the permissions are set correctly on the instance before upgrading, just to rule that out.
These are typically recommended as:
sudo chmod -R 755 .
sudo chmod -R 775 cache custom modules themes data upload
sudo chown -R www-data:www-data .
(replacing www-data with whatever your web server user is)
What about the UpgradeWizard.log file, are there any upgrade-related errors in there that show at the times you have attempted the upgrade?
Additionally, would you be able to give a little more info on what goes wrong, when it does fail?
(ie: Blank Screen / Error on Screen / No option to continue)
Would you be able to send over a screenshot perhaps?
