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!
