HOW-TO recover from beatifulNames uninstall bug

Support and Discussion Plugins
1

I wanted to try the beatifulNames plugin. I installed it but could not make it work (got 500 error immediately). So I removed it. But the CyberPanel interface got broken, constantly forwarding to installed plugins area. So I had to dig a bit. Here is what I found and how I recovered (I’m completely new to CyberPanel and Django).

First of all it is already reported as an issue:

I found that the “remove” procedure was messing with the template, I found it just by looking at the html source code. Steps to correct:

  1. Edit /usr/local/CyberCP/baseTemplate/templates/baseTemplate/index.html
    (I made a backup copy of it before editing)

  2. Near the end find the following code:

                     <div class="sidebar-submenu">

                     <ul>
                         <li><a href="{% url 'installed' %}"
                         </li>
                     </ul>

                 </div><!-- .sidebar-submenu -->

As you can see the anchor tag () got stripped and does not have a closing tag.

  1. Replace it with the original code from github source (cyberpanel/index.html at stable · usmannasir/cyberpanel · GitHub)

                             <li><a href="{% url 'installed' %}"
                                title="{% trans 'Installed Plugins' %}"><span>{% trans "Installed" %}</span></a>
                         </li>

  2. From SSH, restart lspcd

service lscpd restart

That’s it…
I hope this helps somebody…

Here is what I found during examination:

In /home/cyberpanel/stderr.log a couple of the following:
