Update Blog2Social to version 6.5.4 to make sure that you use the latest version available with the latest Blog2Social usability and bug fixes.

Fixes:

• Open graph meta tags: 

Function to calculate the image dimension (height, width) for external images was removed to reduce a possible plugin performance loss when loading images from slow external servers.

• Customization of the PHP warning:

The PHP warning: "Use of undefined constant B2S_PLUGIN_USER_VERSION" was fixed.
