WordPress Post Comment Error – Unreadable Captcha Token File
After upgrading a bunch of WordPress plugins on a site I noticed that comments were not functional on my site for users that were not logged in. This can always be tricky because if someone reports comments not working to the WordPress site administrator they likely will be logged in when they test the comments and think there is nothing wrong. Anyhow if comments are throwing an error and you have the SI Captcha Anti-SPAM WordPress plugin installed then the below content will assist you to resolve the problem.
