Issue with Pages not loading

We performed an update to the OS, and it is now using PHP7.0, and Ubuntu 16.04

Now the site loads, but the site spliays nothing but the main bar on the top. Attaches is a screen shot.

Figure the issue out. It seems after we upated the OS, a couple different things happened.,

The Database switch from MYSQL to Maria… This caused the DB to lose its information. We performed a restore from a backup before the OS update, and it came back to normal.

PHP lost a couple dependenciesneeded. . I had to run ./composer update inside of /opt/librenms/ to grab all dependencies needed. Then run ./daily.sh and fix any other issues that arose.

Some other things are still broken. The biggest being Email alerting. But i guess its my fault for letting the server get so far behind updates. Is there old documentation somewhere available for me to look at? All the documentation now is for todays systems… It would be nice anyways.

Thanks
