7. Go to jCenter >> Apps >> click "Check" button and then update again.
A fatal error occured during the install process. Contact the support with the message below:
Fatal error: Call to a member function nameQuote() on a non-object in C:\xampp\htdocs\community2\joobi\node\library\class\table.php on line 1992
Also one doubt:
-You say "Update again" in step 8, however until step 7 there is no "update" instruction. So, what is that "again" meaning?
