Unable to Edit Views

Hello guys, I am using opigno for my website development and I like it very much I have one problem while editing the views. Whenever I create a new view and try to edit fields or try to add filters I get a page full of errors. It is not a drupal or opigno page it is just a page where all content is thrown. Errors start like this: {"command":"settings","settings":{"basePath":"\/opigno\/","p..... and end at \u0022Add Page\u0022 \/\u003E\u003C\/div\u003E","settings":null}] Log message gives this: Notice: Undefined index: path in theme_opigno_simple_ui_local_task() (line 278 of /var/www/opigno/profiles/opigno_lms/modules/opigno/opigno/modules/simple_ui/opigno_simple_ui.module). What is the error? How can I create my own views? Is this a problem related with my theme Please help me guys! I need urgent help? :(
