Argument #1 ($stream) must be of type resource, bool

[bassangler]

I'm getting this error ever since I upgraded to the latest version 4.7.3 (theme was updated too).

 

TypeError: flock(): Argument #1 ($stream) must be of type resource, bool given in /system/Theme/Cache/Template.php:90

Where is it you are seeing this on the site? Also could you please check this on a default unaltered theme, and ensure all 3rd party items are disabled?

Should catch the \TypeError exception thrown by flock() and/or check if $f isn't bool before using flock().
