Hello. Latest build (commit [0adaa7c](https://github.com/discourse/discourse/compare/a0daa7c...tests-passed)) brings it back after some years 😉
It comes right after the `discourse-presence` plugin is integrated and enabled by default. Should I remove it from the list? I have renamed it so it looks like
I thought it failed because I changed the container configuration without running `./launcher rebuild app` but then I ran it and:

On the server-side nothing’s wrong. The **`/logs/report_js_error`** contains only `OK` which gives a syntax error. See screenshot below.

`fatal: destination path 'discourse-presence' already exists and is not an empty directory.`
So I guess I have to remove mention of this plugin…

Yes, discourse-presence is now part of core, so you need to remove the line from your app.yml file

Indeed, while you replied I went:
```plaintext
cd /var/discourse
./launcher start web
./launcher enter web
cd plugins
mv discourse-presence/ discourse-presence-legacy
^D
./launcher rebuild web
```
The rebuild continued, but the error was still there. Having the legacy code in the way caused problem.
So I removed the line entirely as you suggested, and it’s rebuilding now…

No luck… It looks like a bug…

What is the purpose of this file? Does this syntax error come before or after another error?

rebuild from `master`: works.
Still have an error though in the console:

You need to remove it from app.yml.

Is this the console on the `/admin/upgrade` page? If so you may have hit this issue:

No it’s the console on any page, running the master branch at [PERF: Remove `Object#present?` check introduced in https://github.com… · discourse/discourse@58321d0 · GitHub](https://github.com/discourse/discourse/commit/58321d0783b29d5fbac92eb4404d4d63616c407a) (the one after your fix to that bug you mention.)
[Commits · discourse/discourse · GitHub](https://github.com/discourse/discourse/commits/master) still mentions the build failing… I’m going to wait until `test-passed` includes your fix to revert to that branch.

If the `Discourse.markdown` error is on every page then maybe it’s not the same issue. What plugins do you have installed?

OK, thanks for your interest @david, but I guess it’s a different topic. I resolved the blank page issue by switching to the `master` branch that includes your reverts. Now, on the `master` branch, there’s still this Markdown issue that doesn’t seem to affect much of the site use.
Since you asked, here’s my list of plugins:
```plaintext
hooks:
after_code:
- exec:
cd: $home/plugins
cmd:
- mkdir -p plugins
- git clone https://github.com/discourse/docker_manager.git
- git clone https://github.com/discourse/discourse-spoiler-alert.git
- git clone https://github.com/discourse/discourse-voting.git
- git clone https://github.com/discourse/discourse-solved.git
- git clone https://github.com/discourse/discourse-assign.git
- git clone https://github.com/lidel/discourse-openstreetmap.git
```
I suppose the last one is the culprit since the others are official.

That is a good supposition.

Much has changed since then.

Today I switched back to `tests-passed` from `master` and all is working again. I suspect the patch @david was mentioning in [response #8](https://meta.discourse.org/t/blank-page-after-upgrade-and-javascript-error/69548/8?u=hellekin) was causing the blank page. [All izz well](https://www.youtube.com/watch?v=S-LltgOtFSg) now.

The same happens because of a issue in discourse-encrypt (debounce). See [DEV: Use the new discourseDebounce function wrapper. (#54) · discourse/discourse-encrypt@cf8f995 · GitHub](https://github.com/discourse/discourse-encrypt/commit/cf8f995689d336ff9cd8fd375c9fdc11ece3fcca)
I guess you need to pick an older version of discourse-encrypt in 2.6
