Hello,

i updated odoo 11 to odoo (11.0.20190405) from (11.0.20190214). Afte the update all odoo apps except for the website result in a blank page with only the top menu showing up but with no entires. Checking the browser console i get the following javascript error: 

QWeb2: Can't clone undefined template FieldMany2ManyTag

When checking the log file i can see the following recurrent error line:

  File "/usr/lib/python3/dist-packages/odoo/addons/web_editor/controllers/main.py", line 99, in export_icon_to_png
    addons_path = http.addons_manifest['web']['addons_path']
KeyError: 'web'

Any help would be highly appriciated thanks!

It seems like the problem was caused by an addon: mass_editing_v11. I removed this addon and now everything seems to be working fine.

can you check if the web module is inside the addons path/folder as configured in odoo configuration file?

May be you can upgrade the website/web module after restarting odoo server
