Hi,
One possibility for doing this could be scheduling posts rather than publishing posts. When you schedule posts for a future date (even if that date is just several minutes into the future), WordPress will publish the posts programmatically and should also tell Tumblrize to initiate an action to cross-post the post you’ve scheduled.
But sadly, since the plugin was a labor of love, I haven’t had the wherewithal to maintain the now three-year old codebase.
Recently, Tumblr turned off version 1 of their API, and this means Tumblrize no longer works at all. The original developer has therefore officially announced end of life for the plugin. Neither of us have the time to continue maintaining the plugin and therefore have no plans to write an updated version or a replacement.
At this time, we know of no alternative for Tumblrize, and we apologize for the loss of this tool. However, if you or someone you know would be interested in maintaining a newer version of the plugin, you’re welcome to fork the codebase from GitHub and make whatever modifications you wish, provided you adhere to the software license.
Thank you for using Tumblrize and we hope you continue enjoying using WordPress and Tumblr. ??
Cheers,
