incompatible to sprintdoc template about acmenu

[tormec]

I desperately need to either disable the template or acmenu plugin

If you have access to /lib/plugins, you can manually remove the AcMenu' s folder or clear the cookies associated with AcMenu plugin (in Firefox: right-click and select "Inspect Accessibility Properties", select tab "Storage" > "Cookies" and delete (right click on) the cookies "plugin_acmenu_open_items".)

null array error at line 390 in AcMenu code

I'll try to reproduce this issue with that template.

I'm also affected by that issue, first in line 390, then in line 405. I'm using the sprintdoc template too:
