Section name not being included in breadcrumb

Solved General Discussion
  • No no no no no. Comment out the line with var meta. The one that shows up at the top of the error message you posted. Make sure you uncomment all of those other things.

    This is not a bug in NodeBB. As the error message clearly says, the variable meta was already declared in that scope in library.js. (As const meta ...)

  • @pitaj I'm really sorry for making this thread long and I appreciate you take your priceless time to me.

    I checked load.js and index.js and they have no lines containing with var meta. They just have const meta = require('../meta');. You can check them in Github repo too:

    I intended to comment out lines with var meta, but I found nothing.

    In the error message

    2021-03-04T17:05:46.584Z [4567/600] - error: /some_path/node_modules/nodebb-theme-persona/library.js:37
    var meta = require.main.require('./src/meta');

    You need to edit the same file you've been editing the whole time: /some_path/node_modules/nodebb-theme-persona/library.js

    You need to comment out line 37, the one that starts with var meta as shown in the error message.

  • @pitaj I did this and I get error at line 15:

    error: /category/5/%D9%BE%D8%B1%D8%B3%D8%B4-%D9%88-%D9%BE%D8%A7%D8%B3%D8%AE
    ReferenceError: relative_path is not defined
        at Object.helpers.buildCategoryBreadcrumbs (/some_path/node_modules/nodebb-theme-persona/library.js:15:14)

    Error in my forum is:

    relative_path is not defined

  • @inna okay try adding this below the const meta = ... line:

    const relative_path = meta.config.relative_path;
  • @pitaj thanks, it's fine now, but there's an issue in the breadcrumbs links.
    Because my forums names are in Persian, there may some ASCII URLs.
    For example, link itself is fine, but when I go to it and I check the breadcrumbs links (category 5 is 2 levels up after the main site), its previous category link is and Home link is .
    To see this, I remain these changes in my website.
    This is log of Nodebb:

    [ { text: '[[global:home]]', url: 'undefined/' },
      { text: 'پایتون ۳', url: 'undefined/category/3/پایتون', cid: 3 } ]
    [ { text: '[[global:home]]', url: 'undefined/' },
      { text: 'قوانین، اطلاعیه‌ها و اخبار',
        url: 'undefined/category/1/قوانین-اطلاعیه-ها-و-اخبار',
        cid: 1 } ]
    [ { text: '[[global:home]]', url: 'undefined/' },
      { text: 'قوانین، اطلاعیه‌ها و اخبار',
        url: 'undefined/category/1/قوانین-اطلاعیه-ها-و-اخبار',
        cid: 1 } ]
    [ { text: '[[global:home]]', url: 'undefined/' },
      { text: 'پایتون ۳', url: 'undefined/category/3/پایتون', cid: 3 } ]

    Also if you remember and told me to add a console.log(breadcrumbs), it's still in the file but there's no output in the console tab.

  • @inna okay it looks like the solution I gave was incorrect, but at least you aren't getting errors.

    meta.config.relative_path is wrong (which is why you see a bunch of undefined). Try this instead:

    const relative_path = require.main.require('nconf').get('relative_path');
  • @pitaj thanks a lot, it works fine:)
    Thanks a lot for helping me.

  • @inna you're welcome!

    Do you mind posting the final code so others may use it as a reference?

    Also I must recommend you move that code into your own custom plugin, as otherwise you may lose your changes. For instance, when upgrading NodeBB that file is likely to be overwritten.

  • @pitaj Sure, why not:)
    In the path /to_your_nodebb_path/node_modules/nodebb-theme-persona/library.js (or whatever file and path you want to add), after the first line which is 'use strict';, add these lines below the first line:

    const helpers = require.main.require('./src/controllers/helpers');
    const categories = require.main.require('./src/categories');
    const meta = require.main.require('./src/meta');
    const relative_path = require.main.require('nconf').get('relative_path');
    helpers.buildCategoryBreadcrumbs = async function (cid) {
    	const breadcrumbs = [];
    	while (parseInt(cid, 10)) {
    		/* eslint-disable no-await-in-loop */
    		const data = await categories.getCategoryFields(cid, ['name', 'slug', 'parentCid', 'disabled', 'isSection']);
    		if (!data.disabled) {
    				text: String(,
    				url: `${relative_path}/category/${data.slug}`,
    				cid: cid,
    		cid = data.parentCid;
    		if (meta.config.homePageRoute && meta.config.homePageRoute !== 'categories') {
    				text: '[[global:header.categories]]',
    				url: `${relative_path}/categories`,
    			text: '[[global:home]]',
    			url: `${relative_path}/`,
    	return breadcrumbs;

    Then comment out line starting with var meta by adding two //:

    //var meta = require.main.require('./src/meta');

    Then you can restart by either of these ways:

    • /nodebb_path/nodebb restart
    • service nodebb restart
    • systemctl restart nodebb

    Regarding custom plugin, I'll consider it soon.
