Hi folks, the quickest fix is to disable the display_errors setting in PHP. That shouldn’t really be enabled on a production site as you can leak sensitive information about your site.

At any rate, I’ll check into it and give you an update soon.

+1 started showing up everywhere. Unfortunately not every site operator has control over PHP settings

@dimchik Indeed, though in such cases, one would like to hope that the webhost would configure it with this warning in mind (direct from the official/stock php.ini):

Error output is very useful during development, but
it could be very dangerous in production environments. Depending on the code
which is triggering the error, sensitive information could potentially leak
out of your application such as database usernames and passwords or worse.
For production environments, we recommend logging errors rather than
sending them to STDOUT.

Alas, I realize we don’t live in a perfect world, so some are stuck with webhosts that don’t make sane choices ??

Version 5.1.1 is released with the fix!

thanks for nosilver4u, i’ve updated to 5.11 and also turn off display_errors settings in php set
it solved now
