After changing the theme of the Juniper installation, a few **pages are broken**. Some of the issues are as follows.

1. The clickable stuff(for example: _Expand all_, Course content items etc.) are not responding to  
click.  

2. The course-content are not loading.  

3. There are a lot of **JS errors in the console**.  

This is happening with red-theme and dark-theme as well as my custom-theme. It looks like some of the **javascript files are not loading** but I am not sure why.

These are the steps I followed:

First, I edited following values in the **/edx/etc/lms.yml** and **/edx/etc/studio.yml**.

> “COMPREHENSIVE\_THEME\_DIRS”: [  
> “/edx/app/edxapp/edx-platform/themes”  
> ],  
> “DEFAULT\_SITE\_THEME”: “red-theme”,
> 
> “ENABLE\_COMPREHENSIVE\_THEMING”: true,

Then I ran the following commands:

> sudo -H -u edxapp bash  
> source /edx/app/edxapp/edxapp\_env  
> cd /edx/app/edxapp/edx-platform  
> paver update\_assets lms --settings=production  
> paver update\_assets cms --settings=production  
> exit

> sudo /edx/bin/supervisorctl restart lms  
> sudo /edx/bin/supervisorctl restart cms  
> sudo /edx/bin/supervisorctl restart edxapp\_worker:

I think there is some issue with the commands I am using to update the assets but don’t exactly know what is the issue. Could someone please help with this? Thank you.

Sometimes it happens to me that some static resources are not collected correctly.  
try the following commands within the edxapp venv:

```auto
# enter the edxapp venv, same as before
sudo -H -u edxapp bash
source /edx/app/edxapp/edxapp_env
cd /edx/app/edxapp/edx-platform

# collect static assets again for lms and cms
./manage.py cms collectstatic --noinput
./manage.py lms collectstatic --noinput

# feel free to exit ...

```

If you use an 8GB ram server, your update\_assets command might finish with an error (not enought memory). As precaution I always stop lms service to free so ram then start it again once the task is finished

```auto
/edx/bin/supervisorctl stop lms
# do your update_assets stuff here
/edx/bin/supervisorctl start lms

```
