I have just installed easyblog 5 and have written a post. I saved it as a draft and then edited it. When ready I clicked on 'publish post' and it said your post is saving. Hoever the post remains as a draft and there is no way to publish it. I then tested it by writing a test post and clicking 'publish post' without saving a draft first and it said the post was saving again, but this time the post was not saved and all the content lost.
I also tried the preview button and the system said it was saving the post but no preview appeared.
I see lots of other users are having similar issues and it would be good to know if there is a solution.

UPDATE
I just tried changing the editor to JCE and saved the post and this time it said the post had been published successfully- and indeed it has - not sure if this helps
