Error while upgrading from 3.8.4 to 4.0 Gold.

[ganesh177]

Hello folks,

I just did the upgrade from 3.8.4PL2 to 4.0 Gold, and i have a error to welcome.

The upgrade process showed that everything was upgraded fine. But opening homepage shows this error.
Same error on contol panel too, but i can see the left panel though, but the same error on main right panel.
Hence i am not even able to check if any mod/plugin is causing any problem.

Warning: fetch_template() calls should be replaced by the vB_Template class in [path]/includes/functions.php on line 3895

Fatal error: Call to a member function hide_errors() on a non-object in /home2/worldne4/public_html/includes/class_bootstrap.php(283) : eval()'d code on line 45

Please help ASAP.

Thanks for patience.

Disable plugins and then see. If you are running vbseo disable it ..

I had the same problem. I disabled all of my plugins via config.php, went into my admincp and uninstalled them all, and everything was good.

Also, be aware that a security patch was just released that involves function.php
