Reply To: Data are not saved into the database.

Hi Vadym,

Thanks a lot for your links. I've tested again and experienced the same problem. This issue is something related to the way Gutenberg saves data from TinyMCE editors. It's a bug in the Gutenberg and was reported here. The developer team seems not to have a final solution at the moment. The only workaround is running window.tinyMCE.triggerSave() before saving posts.
