@baris I found what causes trouble.
I switched from Lavender to an other theme, and it works...
I tested all others themes, the problem comes from Lavender.
Thanks for helping me 👍 💋
We need better messaging, select a category first and it will work.
This is fixed, will be available in 1.7.1 https://github.com/NodeBB/NodeBB/issues/6073
If category is not selected entered tags just disappear
Great, thanks guys! we will try to update.
Yeah, this is totally not a new issue and has been posted about more than once in the past. Glad something was done.
The same problem comes with pasting in images. it uploads to the browser, then fails if there is no category selected first. Also been discussed before.
