Once v0.9.0 is released, these emailer version mismatches will be dealt with... 😄
Thanks i too am having similar problems
whenver I am doing ./nodebb status
this is coming : -bash: ./nodebb: Permission denied
hence I am not able to start nodebb
@Abhinov-Singh-0 I suggest learning about solving Linux permissions issues on your own.
For now, I'm guessing you need to make it executable:
chmod +x ./nodebb
It may also be an issue with ownership, in which case you'd use chown.
You can search for any of these topics and find hundreds of tutorials.
