I am running an OwnCloud server on my one.com web hotel. The databse is running on MariaDB. For the last three days I have been getting "500 internal server error" when trying to acces the site. My sync clients cannot connect either. The only thing I have done differently is about a week ago I started using a sync client for Ubuntu, I had alot of problems with it, stopped syncing, had to reboot alot. When I think back, it was probably the server being flaky.
Since all the logging happens in MariaDB im not sure what to do. I have seen alot of "Aborted clients" and "Aborted connects" in PHPMyAdmin. But I am not sure if this is the cause, or how I would go about fixing it.
Im adding a couple screenshots from PHPMyAdmin: Screenshots
ALso, owncloud has stopped development; been forked into Nextcloud. OP will likely not see updates to your server running owncloud. You should switch to Nextcloud.
I dont even know that kinda web server or OS its running (derp). I dont have any terminal access. I conencted with FTP and I couldnt find any logs in the standard locations like /var/log.
