I recently had to change the internal IP range of my network and that included my WordPress hosting server. I thought that I could just update the database and config file and the site would work, wrong!! The home page would display but every page and link was broken and there was no formatting and the uploaded content no longer displayed. Also when trying to login the site was still trying to access the old url as I was accessing the site by IP as it was only a testing site. I never did manage to fix the error despite an hour of my time, in the end I just had to create the a new site on the new IP and then copy the content over.If anyone else has come across this and knows how to resolve it please let me know!
Well, been talking about it for a while, but finally got around to building an NGINX/LEMP stack. Only took a couple of hours with help from this site https://digitalocean.com/community/tutorials , including the basic hardening config. Will post a tutorial soon!
