It doesn't work

Hi Shalun,

Thanks for the notification. What exactly happens when you compress an image in WordPress? Do you see any messages in the list view of the media browser?

The only requirements to run the plugin successfully are a working WordPress installation that has either cURL or fopen support.

Thanks!

Hi

No messages at all

The plugin is installed, API key is input

Could you please email us a screenshot of the list view in the media browser to support@tinypng.com?

Hi

Now there are messages

Compressed 0 out of 2 sizes
Latest error: error:0D0890A1:asn1 encoding routines:ASN1_verify:unknown message digest algorithm

Ah, that gives us something to work with!

It seems the version of OpenSSL that cURL is using is too old to verify the SSL certificate we are using.

I would suggest you to update OpenSSL and cURL on your system to the latest version.

For references, please see:

Thank you.
That’s what I suggested – old server soft.

Thank you for great web service and plugin.
