no graphs after upgrade ubuntu server and new cacti 1.2.27

[miraaj]

Hope u r doing well
I installed an ubuntu server and upgrade it to 24.04 and installed on it cacti 1.27. with php 7.0, apache, and mariadb every thing works fine .But when I imported the old mysql database and rrd file, I got a new webpage to reset cacti and went through it smoothly but at the end , I have old graphs but the guy is not pulling new graphs, it s empty.

before importing old things it was pulling graphs on my test devices I added.

Any errors in the cacti log? Most likely its a permission issue on the rra folder and it can't create the new rrd files. You can attempt to use the Troubleshooter built in to Cacti. You will find it under Console > Troubleshooting > Data Sources.

You have more problems:
1) Fontconfig error: No writable cache directories - check /path/to/cacti/cache/* permissions. Webserver needs write permisssion here.

2) SYSTEM WARNING: Primary Admin account does not have an email address - set correct email address in configuration -> users -> admin. You have be notified about problems

3) SYSTEM STATS: Time:299.1216 - your poller doesn't finish on time. Check forums, it has been here many times
