thank you for your answer , i have done your recommendation but :

from flask_themes import setup_themes, render_theme_template

python /opt/qpanel/app.py
Traceback (most recent call last):
File "/opt/qpanel/app.py", line 1, in <module>
from qpanel import app
File "/opt/qpanel/qpanel/app.py", line 8, in <module>
from flask_themes import setup_themes, render_theme_template
ImportError: No module named flask_themes

when i check lib i cant found this directorie "flask themes" in /usr/lib/python2.7/site-packages only this file /usr/lib/python2.7/site-packages/Flask_Themes-0.1.3-py2.7.egg
