I used the following to stop Solr plugin, then rebuild, then it works.

./nodebb reset -p nodebb-plugin-solr

I do remember that when I was upgrading nodebb, it said solr will be upgraded. Then I upgrade solr. But it looks the new version of solr doesnot work well, at least for my server.

One year ago I met the problem of Solr, back then I installed solr manully. I am not sure if it is the same problem this time.

I tried to build it again, yes, once I install nodebb-solr by the following command, and active it in the ACP, then I cannot open /admin page.

npm install nodebb-plugin-solr

as soon as I remove it by

npm uninstall nodebb-plugin-solr

I can open ACP page. I am using nodebb v1.18.6. I find this solr plugin was updated recently from 5,3,0 to 5.3.1, I think maybe there is a bug?

Alright, right now I use the following to fix it:

npm install [email protected]

Now it works.
