OPNSense 26.7 Squid web gui összeomlik

Temporary workaround until this is fixed. Guard the subtab loop in /usr/local/opnsense/mvc/app/views/layout_partials/base_tabs_content.volt:

-    {% for subtab in tab['subtabs']|default({})%}
+    {% for subtab in tab['subtabs']|default({})%}{% if subtab[2] is defined %}
             <div id="subtab_{{subtab[0]}}" class="tab-pane fade{% if formData['activetab']|default("") == subtab[0] %} in active {% endif %}">
                 {{ partial("layout_partials/base_form",['fields':subtab[2],'id':'frm_'~subtab[0],'data_title':subtab[1],'apply_btn_id':'save_'~subtab[0]])}}
             </div>
-    {% endfor %}
+    {% endif %}{% endfor %}

make a backup first
sudo cp /usr/local/opnsense/mvc/app/views/layout_partials/base_tabs_content.volt /root/base_tabs_content.volt.bak

change the content

sudo sed -i '' \
  -e "s/{% for subtab in tab\['subtabs'\]|default({})%}/{% for subtab in tab['subtabs']|default({})%}{% if subtab[2] is defined %}/" \
  -e 's/^        {% endfor %}/        {% endif %}{% endfor %}/' \
  /usr/local/opnsense/mvc/app/views/layout_partials/base_tabs_content.volt
