Thank you for the verification suggestions.
Indeed, by consulting the file "instance-script.py. I have this:
"#!" C: \ Plone43 \ python \ python.exe "-S
sys.path [0: 0] = [
'C: \ \ \ Plone43 body parts'
path = sys.path 
if os.environ.get ('PYTHONPATH'):
path = os.pathsep.join ([path, os.above ['PYTHONPATH']])
os.environ ['BUILDOUT_ORIGINAL_PYTHONPATH'] = os.environ.get ('PYTHONPATH', '')
os.about ['PYTHONPATH'] = path
import site # imports custom buildout-generated site.py
if name == 'main':
sys.exit (plone.recipe.zope2instance.ctl.main (
["-C", 'C: \ Plone43 \ parts \ instance \ etc \ zope.conf']
sys.argv [1:])) "
So obviously the name of the instance is "'C: \ Plone43 \ parts \ instance'"
But by consulting the folder "parts", the folder "instance" is missing. There is only the "buildout" folder.
By checking in the backup performed before starting the update to plone 4.3.15,
I find bein the folder "instance".
So this folder was probably deleted when trying to update to plone 4.3.15?
How can I fix this bug?
Can I copy the "instance" folder from the backup folder and add it to the "parts" folder in the Plone43 installation directory?
Thank you in advance for your answers.
