Hi there,
Your plugin may have been the cause that my menu items threw an error (Call to undefined method JModuleHelper::isAdminMultilang()] ) after the last upgrade to Joomla 3.8 from 3.75
In fact disabling it restored my menu items. I'm using T3 Framework, don't know if has something to do with it. There are quite a few people with this error, some of which have restored their entire database. I added my response to the end of the thread.
Please see: https://github.com/joomla/joomla-cms/issues/18003
Thanks for getting back to me asap because I'd LOVE to have my icons back!;-)
Elisabeth
