Recently, Burn Engine updated and created numerous problems such as:
1. Header and Footer code has been removed
2. We no longer have access to Modules/Extensions
3. Can not update quantity in cart

While there are more issues, we were at least able to see our website and access the admin area.

Just now, we only see this message when going to the website:
– There BurnEngine module has not been installed. Please, enter the admin area and install it.

And in the admin area we are seeing:
BurnEngine has not been installed due to the following reason(s):
The engine cannot find at least one valid theme.
Please, correct the errors above and then try to install the theme module again

Please help!
