Red Graphs and Other Oddities

So yesterday i managed to fumble through updating my PHP version. Initially i just installed the new PHP version but that ended up giving me a bad gateway error. After spending too much time editing the www.conf and librenms.conf files i decided to just uninstall everything php related and reinstall 7.2. This seemed to work for the most part. i was able to get back to the application so i proceeded to update using and i also proceeded to update the DB schema as well. once i got the validate.php all green i hopped in to the application to take a look and that’s when i noticed all my graphs were broken. also, i’m not able to see any of my alerts. although i still get alert emails, they don’t make any sense (ex: "Rule: {if %name}%name{else}%rule{/if} ").

Here is the output of validate.php:


Component Version
LibreNMS 1.49-54-g3905423
DB Schema 2019_02_10_220000_add_dates_to_fdb (132)
PHP 7.2.16
MySQL 5.5.60-MariaDB
RRDTool 1.4.8

[OK] Composer Version: 1.8.4
[OK] Dependencies up-to-date.
[OK] Database connection successful
[OK] Database schema correct

And make sure the web server has permissions to the php session folder.

not sure if that had anything to do with the issue. in the end it actually appeared to be a cookies/cache issue. After clearing those things started working again.
