A couple of updates ago, I happened to notice that I could no longer access my discourse forum www.nzarchitecture.net.nz, from any of my Android 10 smartphones, or from my Chromebook or from any windows PC (except on one where I was already logged in) The site stops loading while trying to invoke the login dialog, displaying the ‘loading’ coloured dots graphic endlessly. [download|0x0] I have tested on three different Samsung Galaxy S9+ phones (all in my family have same phone) using Brave, Chrome, Edge and Samsung’s own preinstalled browser. No change via an incognito (safe mode) browsing window. Unfortunately I don’t know exactly which Discourse update might have caused the problem as I seldom log out deliberately, and my daily driver windows machine happens to be permanently logged in so bypasses the login dialog when I normally access the site Is this a known issue, and is there a fix? Perhaps something to do with browser popups?

Oh actually, I cannot load http://www.nzarchitecture.net.nz/ either (latest Chrome, macOS), so I don’t think this is a browser-specific problem. The browser console shows an error with discourse-merge-users. That plugin is deprecated, so your forum administrator needs to uninstall it. [image] Merge Users Plugin Plugin warning As of Discourse 2.5.0 beta 3 Merge users is built into Discourse warning See: Discourse 2.5.0.beta3 Release Notes This plugin will not be supported long term and may break soon.. Update Dec 2022: I think a recent software update has meant that the plugin causes an error when someone is not an admin: Unhandled Promise Rejection: Error: Could not find module admin/models/admin-user imported from discourse/plugins/discourse-merge-users/discourse/components/merge-users-form So if …

Confirm that the site is not loaded in Ubuntu, Win10 and Android 10 (Firefox).

Hi, one example where the login dialog can not open is on Chrome 109 What browser am I using? But as noted above the issue also affects Edge and Brave on both Windows 11 and Android 10, and Samsung’s own browser on Android 10. I just now tested, and it also affects Tor browser (12.0.1) under Windows 11 I have previously tried to regenerate the site using cd /var/discourse git pull; ./launcher rebuild app ./launcher cleanup but again no change - so assumed my installation is not corrupted. Given that other people’s discourse sites still seem to work, does this suggest there must be some incompatible new setting associated a recent update?

Someone else had this issue with Merge Users recently too: [image] After update, site won't come up Self-hosting I got an email notification the other day that my self-hosted Discourse site (Ubuntu 18.04.6 on Contabo) was due an update, so to the Admin page I went to update. As usual, I first needed to update docker-manager, and then run the rest of the update for the site. That update seemed to freeze in place–it reached a certain point, and then didn’t move at all. After about an hour of that, I figured CLI intervention was called for, so I ssh’d into the server and did cd /var/discourse; git pull; ./…

[image] David Taylor: The browser console shows an error with discourse-merge-users. That plugin is deprecated, so your forum administrator needs to uninstall it. That is going to be a problem - I previously tried to uninstall that plugin a year or so ago, and broke the site as a result, and was forced to restore from backup. And of course now that I have logged out with all my testing, I can no longer log back in to try disabling the plugin again.

Disabling a plugin via admin doesn’t totally disable it. You’re going to need to remove it from your yml file and rebuild via the terminal. Merge users as a plugin is deprecated now, the feature has been native to discourse since 2.5.

This link should help with getting logged in: https://nzarchitecture.net.nz/login?safe_mode=no_plugins (you can add ?safe_mode=no_plugins to any URL) But as @Stephen said, the only way to remove a plugin for sure is to remove it from the YML config and rebuild.

Hmm - my app.yml. file looks different, and has no references to plugins that I can see. Putty console session below, in case that helps root@nz:~# cd /var/discourse root@nz:/var/discourse# nano containers/app.yml GNU nano 2.9.3 containers/app.yml ## this is the all-in-one, standalone Discourse Docker container template ## ## After making changes to this file, you MUST rebuild ## /var/discourse/launcher rebuild app ## ## BE *VERY* CAREFUL WHEN EDITING! ## YAML FILES ARE SUPER SUPER SENSITIVE TO MISTAKES IN WHITESPACE OR ALIGNMENT! ## visit http://www.yamllint.com/ to validate this file as needed templates: - "templates/postgres.template.yml" - "templates/redis.template.yml" - "templates/web.template.yml" - "templates/web.ratelimited.template.yml" ## Uncomment these two lines if you wish to add Lets Encrypt (https) - "templates/web.ssl.template.yml" - "templates/web.letsencrypt.ssl.template.yml" - "templates/import/mysql-dep.template.yml" ## which TCP/IP ports should this container expose? ## If you want Discourse to share a port with another webserver like Apache or nginx, ## see https://meta.discourse.org/t/17247 for details expose: - "80:80" # http - "443:443" # https params: db_default_text_search_config: "pg_catalog.english" ## Set db_shared_buffers to a max of 25% of the total memory. ## will be set automatically by bootstrap based on detected RAM, or you can override db_shared_buffers: "128MB" ## can improve sorting performance, but adds memory usage per-connection #db_work_mem: "40MB" ## Which Git revision should this container use?

How was this instance installed? Are you using two-container?

Hi, just one container (at least as far as I know) To be fair I know and understand nothing about Linux… I do know I have a single Digital ocean droplet - is this the same thing as a ‘container’?

There’s quite a lot more to that file, scroll down. Plugins are in the hooks: section around line 94. If you’re in nano use Ctrl+ _ to jump to a line number or nano +94 app.yml
