Issue no menu, login window or buttons after upgrade from 26.x.x to 27.x.x, only the frame of the website

FLS · November 17, 2023, 9:33am

Hello Community,

I have a strange behaviour in one of the clouds I am supporting. I have good experienses over along time with nextcloud. Actually I support six different instances, all are always up to date. Nearly all problems in the past, I was able to solve by myself, because nextcloud is well documentated as you know.

I have this behaviour only in one of my instances, all the others are fine. But I could not find the reason for it. It is a cloud with many users (more than 100), so I use the updater via commandline. The updateprocess is running to the end without any errors, everything seems to be fine.

After the update is performed I have the following problem:

if my browser has catched my Login, only the frame of the website is visible, but there`s no other function visible like the folder button, the menu link, notifications and so one, the frame is blank
if I am not authenticated in the browser on the loginpage, the prompt and fields are even not visible

I don`t know what is causing this issue, clean the browsercache, changing to different browsers (tested with Edge, Firefox and Chrome) did not change anything on this.

Nextcloud version: 26.0.8
Operating system and version : Ubuntu 20.04.6 LTS
Apache: 2.4.41
PHP version : 8.2.12

The issue you are facing:

Is this the first time you’ve seen this error? (Y):

Steps to replicate it:

Start Nextcloud Update via commandline
Perform the update
Open Website of Nextcloud instance

The output of your Nextcloud log in Admin > Logging:
Hint: I guess this is not helpful, because after the update is performed, logging is stopping here too, this is the last entry, there is no error hint to see in this log

{"reqId":"pVkM6bwWoE9TDfn1UvHU","level":1,"time":"2023-11-17T06:58:08+00:00","remoteAddr":"","user":"--","app":"updater","method":"","url":"--","message":"\\OC\\Updater::resetLogLevel: Reset log level to Warning(2)","userAgent":"--","version":"27.1.3.2","data":{"app":"updater"}}

Additional, and may be more helpful, here is the updater log, but I can see no error here:

The output of your Apache2 log in :

error log is empty, everything seems to be fine here too

So, if someone has an idea what is faulty here, it would be great.

I compared permissions and settings, php versions, php modules and so on to the other servers and instances, but I`m running in cycles.

I hope someone can help me with this,.

Can you check the browser developer tools, if it fails to load some resources?

Do you use a customized theming?

FLS · November 21, 2023, 7:36am

Hi tflidd,

both hints are good ones, thank you.

Yes, in this cloud I`m using customize themes and I found some empty strings in the configuration. I corrected this, but the behaviour was the same. Even if I go back to the default themes of nextcloud, no changes.

Your first hint to check what the browser develpement tools say brings me a new information. It seems like no js libarys can be load after after the update.

But till now I dont know why js is not loading, this could be a hint that theres something wrong with the proxysettings in the cloud, but I cant prove it, this proxyconfiguration worked for round about 10 years without any issue, I will write it down here again, if I know more.

tflidd · November 21, 2023, 10:14am

Regarding javascript, there was a change:

github.com/nextcloud/server

Allow apps to include module js / ES6 scripts

nextcloud:master ← nextcloud:feat/esm-js-scripts

opened 02:56AM - 10 Jan 23 UTC

susnux

+164 -52

## Summary Allow apps to provide scripts as ES6 modules by adding a `type="modu…le"` to script tags of module files. This is done by changing `JSResourceLocator` to also look for `.mjs` files, and fallback to `.js` (this allow app developers to provide both files so their apps can be used even on Nextcloud version not supported this feature while using the modern scripts on new Nextcloud versions). The benefit of this is apps are no longer required to rely on module loading from webpack & co but can utilize the module loading of the browser (fully supported by all of our browser targets). Moreover this allows to create much smaller bundles. Example: <details> Below is an example for reduced bundle size of the `forms` app (selected because mid-sized app) | method | with source maps | just code | |-------------|--------------------------|---------| | Currently using webpack for bundling / chunking | `26580 KiB` | `7332 KiB` | | ES6 browser modules (compiled using vite) | `11748 KiB` | `4068 KiB` | </details> But as said it is even possible to now to quit using a bundler at all and let the browser load needed modules, as something like this is possible: ```js // my-app/js/entry.mjs import { someFunction } from './other.mjs' someFunction(); ``` ```js // my-app/js/other.mjs export function someFunction() { /* */} ``` ### Other considered solutions I also considered adding a flag on `OC\Util::addScript` (e.g. an `isModule` parameter). But this would require to rewrite / change a lot of internal utilities as this information must be carried along through the `OC\Util`, the `TemplateLayout` (which also would have to work with deprecated `OC_Util` scripts), the `JSResourceLocator` and then be printed by the template functions. ## TODO - [x] Add documentation to the manuals - [ ] Add support within docker image (mime info and rewrite rules in `.htaccess`) ## Checklist - Code is [properly formatted](https://docs.nextcloud.com/server/latest/developer_manual/digging_deeper/continuous_integration.html#linting) - [Sign-off message](https://github.com/src-d/guide/blob/master/developer-community/fix-DCO.md) is added to all commits - [x] Tests ([unit](https://docs.nextcloud.com/server/latest/developer_manual/app_development/tutorial.html#unit-tests), [integration](https://docs.nextcloud.com/server/latest/developer_manual/app_development/tutorial.html#integration-tests), api and/or acceptance) are included - [ ] Documentation ([manuals](https://github.com/nextcloud/documentation/) or wiki) has been updated or is not required

FLS · November 22, 2023, 9:10am

Hi tflidd,

thank you for the link. You are right, there was a change. After reading the changelog I compared the setting of this cloud with another one with focus on the apache conf and the mime types because of the link you sent me.

After that I renewed the whole apache2 conf and added some missing libapache mods. The mime js mjs was already set in etc/mime.types and grabbed by /etc/apache2/mods-enable/mime.conf too. I renewed all because this is the only cloud where I was not the one who build it. On all other instances, I did everything from installing the os to the nextcloud installation/configuration. This was a out of the box distribution and I overtook this after it was running for a few years, so I like to cleanup step by step things when I find them. And the last years this cloud was running fine with all updates and less problems.

To be sure the mime (js mjs) is really set I temporarely used hard code in .htaccess (which no one should do, if she or he is not knowing what she or he is doing there), but the result is always the same.

I was pretty sure that mimes are the problem while I was reading the article you sent. On the good site is I found some dirty configurations which I could clenaup. But on the bad site is that I am on the start now. I have the same behaviour after an update, can`t find any helping logs, the only thing I can say is that js are not loading anymore after the update, without catching the cause.
