Site Cleanup

I tried and failed to update my site to WordPress 4.6. I did update it by uploading 4.6 files via FTP. It overwrote all the bad files and now the site is running again, but I noticed my admin is slow. I’ve deleted a number of outdated plugins. I’m in the process of deleting other material as well. I’ve deleted my photo pages, and once I download all the pictures I’d uploaded I’ll be deleting the gallery plugin. It’s not needed anymore. I plan to keep my archived podcasts, but I’ll see If I can reformat them in a way to not use the podcast plugin.
