I have moved the options to change the title and messages to XenForo's Phrase System to enable language support. The options are still there but are deprecated and you have to update the phrases if you have changed the value for these fields. Visit the option page to note the phrases that needs to be changed.
And also, I've created a GitHub repo: https://github.com/gfnlabs/link-proxy so if you have an account and want to post a suggestion/issue please use the GitHub issue tracker to make my life a lil' bit easier
NOTE: If you are using the older version, note down all the changes you made and remove the that one before installing the new one. Upgrading will not work as the Add-on ID has been changed.
This will be the last time the Add-on ID for this mod is going to change, I promise
I've re-written the whole code base to remove any kind of bloat. Also changed how the external links were fetched for processing. This add-on now uses 'to' variable to send the proxied link (which is base64 encoded first) to prevent any kind of double encoding and such.
