MongoDB 4.2.7, nodejs 14.6.0, latest master from nodebb repo.
@Abhinov-Singh-0 You can check which NodeBB version you are running by starting NodeBB. The version is one of the first lines output. You can also look inside the
package.jsonfile, which should say the version number.
Regarding your second issue, the git error is suggesting that you've edited the file
public/language/en-GB/category.json. Did you?
You'll want to reset the file back to the version that came with NodeBB. To do this, run
git checkout public/language/en-GB. Remember, this will discard any changes you've made to this file.
Once done, you can run
git checkout v1.13.xagain.
