Hello
When you have created a blog post in frontend, in Composer you can choose to "Preview Post". If you use sh404SEF, the following entry will be created in the URLs table:
SEF URL: blog/preview/preview-test
Non SEF URL: index.php?option=com_easyblog&Itemid=781&lang=fr&layout=preview&uid=113.253&view=entry
The uid is not present in the SEF URL. So after publishing this post, if you modify it (creating a new revision), when you try to preview this new revision, the old one is displayed instead...
Thanks
