I recently upgraded from 2.7.15 to 2.7.16 and encountered a bug that no JCE editori is being displayed in second tab of custom fields.
After downgrading to 2.7.15 things get back to normal.
Images:
1. Custom fields configuration
2-3. Normal state of things in "Autorius" and "Šaltinis" tabs.
4. After upgrade to 2.7.16 no JCE editor on "Šaltinis" tab. Pressing on/off button in top left launches some process and spinning wheel is shown and if I would press "Save" button of the article, entire text of the article is gone.
