I followed all the correct update steps, but the content appears blank.
Check out the errors in the log file.
Did you set correct permissions for files & folders?
Check below too:
this permisions
sudo chown -R www-data:www-data CRM/suitecrm8
sudo find . -type d -not -path “./node_modules/*” -exec chmod 775 {} +
sudo find . -type f -not -path “./node_modules/*” -exec chmod 664 {} +
Set the required permissions (Run all 4 one-after-another)
If you are using the terminal you can do this by running:
find . -type d -not -perm 2755 -exec chmod 2755 {} \;
find . -type f -not -perm 0644 -exec chmod 0644 {} \;
find . ! -user www-data -exec chown www-data:www-data {} \;
chmod +x bin/console
Please have in mind that:
-
The user and group name (in the above example
www-data) needs to be replaced by the actual system user and group that your webserver runs under. This varies depending on your operating system. Common web server users are as follows:www-data(Ubuntu Linux/Apache)apache(Linux/Apache)
-
If the group name differs from the username apache is running with, you may need
0664instead of0644, and2775instead of2755
Hello Pascual,
two more questions:
Do you have custom code in your CRM? (debug this first / try to remove / deactivate this first)
Do you see any error messages in the browser console?
Interesting, Are you sure your web server running on www-data user?
Can you view modules and admin menu or is it just an issue with home page?
Check log files under:
logs/prod
logs/legacy
Yes, I have customizations in the CRM.

It looks like permissions issue (permission denied) .
Is your root set still /public in the apache web server?
Make sure you have downloaded correct upgrade package.
Steps for upgradation:
I’m running it locally, first applying updates with a local CRM suite, before deploying it to production.
That’s correct way to do it.
