I am trying to build a multilingual site with Joomla 3.9. Due to unknown reason, one of the "Home" flag in content languages is set to "NO" and I can't set it back to "YES". And the result is, it can't be seen or be selected in the homepage. But as I added it into system, it was all "YES" in this column and it worked.
Is there any way to set it back to "NO" (except changing it directly in database) or anyone knows what causes this problem? Thanks for any helps!
