Help

This morning i came back to a broken librenms install and it told me to check the librenms log. Validate looks clean.

Hi!
I have the same problem.

I deleted (moved to a backup-folder) the file /opt/librenms/bootstrap/cache/routes.php, after that the gui is loading again.

But when i run ./daily.sh, the file /opt/librenms/bootstrap/cache/routes.php exits again (so i thin it’s getting pulled from git) and i get the error massage like above again. when i delete the file again it works until i run ./daily.sh and so on.

./validate.php and ./daily.sh have no errors

Hope this helps :slight_smile:

last but not least: thank you so much for this awsome software!!!

Make sure your php cli and web version match.

php -v for cli and in the LibreNMS interface: Gear -> About LibreNMS

PHP 7.4.6 (cli) ,

I cant get to the web interface as it has the screen with the red " Whoops, looks like something went wrong." warning.

I got it back, I ran all this and it started working again:

sudo a2enmod php7.4
sudo update-alternatives --set php /usr/bin/php7.4
sudo update-alternatives --set phar /usr/bin/phar7.4
sudo update-alternatives --set phar.phar /usr/bin/phar.phar7.4
sudo update-alternatives --set phpize /usr/bin/phpize7.4
sudo update-alternatives --set php-config /usr/bin/php-config7.4

Perfect. The issue is when using different php versions for cli and web.

thanks for the hint, this was the solution for me.
