This is going to be a short one. We’re using WordPress for multiple pages hosted on our schools rootserver now. They share tons of plugins and themes and it is quite a lot effort to maintain all of those on all pages singularly, so I came up with a solution making this process a lot easier: symlinking all the things! So every page accesses a single folder containing all the files.
- Copy the needed plugin and theme files to another location outside of the several wordpress root directories.
- Symlink the single folder to the original path in your single instances.
- Benefit from having to update only one folder for all instances, instead of n folders for n instances.
