This is a really annoying error that comes up every so often when installing new plugins. At first I thought it was because they weren’t compatible with my version of WordPress. However after spending some time searching for a solution to this issue, I found the solution and it’s super-simple.

If you’re a beginner then this is the easiest and quickest solution to the Could not create directory. /public_html issue when installing a Word Press plugin.
- FTP into your website with one of the more popular programs
- Go into your WordPress directory and navigate to the folder /wp-content/
- Rename the upgrade directory to something like upgrade-old (you may optionally delete it but I prefer this method in case something goes awry)
- Create a new directory named upgrade in the same /wp-content/ folder
- Set permissions on it to 777 – basically give everyone permission to read, write and execute items in this directory. This is typically found under properties if you right-click the directory in some more popular FTP programs (e.g. Core FTP)
- Try to install the plug-in again and voila! It should work.
- Change permissions on the upgrade directory back to 755, a more secure setting to reduce the potential for someone to hack your website
If you know your way around Linux, then the solution is just as simple with a few keystrokes:
- Log in through your server or a program like PuTTY
- Go into your WordPress directory and run the following sequence of commands:
- CD wp-content
- mv upgrade upgrade-old
- mkdir upgrade
- chmod 777 upgrade
- Try to install the plugin through WordPress again and it should work
- Reset permissions with the command: chmod 755 upgrade
