Filter Fiddler traffic

I updated Fiddler and ran into a similar issue. This fixed it for me: http://textslashplain.com/2015/10/30/reset-fiddlers-https-certificates/

Fiddler 1.3.0+ (This is the new build and comes after 4.6.1.5+)

• Click Settings (the cog in the top right hand corner).
• Select the HTTPS tab from the left hand panel
• Click Trust root certificate
• Accept all prompts
• You may need to restart Fiddler

Fiddler 4.6.1.5+

• Click Tools > Options.

• Click the HTTPS tab.

• Ensure that the text says Certificates generated by CertEnroll engine.

  (Note: You may notice that it's not possible to change the engine from MakeCert to CertEnroll, in such case restart Fiddler and start from the beginning, it should show CertEnroll then.)

• Click Actions > Reset All Certificates. This may take a minute.

• Accept all prompts (to remove and re-add certificates)

Fiddler 4.6.1.4 and earlier

• Click Tools > Options.
• Click the HTTPS tab.
• Uncheck the Decrypt HTTPS traffic checkbox.
• Click the Remove Interception Certificates button. This may take a minute.
• Accept all of the prompts that appear (e.g. Do you want to delete these certificates, etc.)
• (Optional) Click the Fiddler.DefaultCertificateProvider link and verify that the dropdown is set to CertEnroll.
• Exit and restart Fiddler.
• Click Tools > Options.
• Click the HTTPS tab.
• Re-check the Decrypt HTTPS traffic checkbox.
• Accept all of the prompts that appear (e.g. Do you want to trust this root certificate)

I think this is probably just one of many potential solutions for this, but it's coming up as one of the top search results for "your connection is not private fiddler" so I'll add it. Hopefully it'll help anyone else who comes across it.

NOTE: A few people have commented that they needed to restart Fiddler after running the above.

You never close the function plugin_admin_init.

You're missing a closing brace } before the final ?> in your code.
