I have patched my site with the line 149 hack but still having an issue with a plugin.
I am using the Brick theme which requires the “WPBakery Visual Composer” which seems to actually be called “js_composer” when installed — but when it’s installed I get errors:
[Mon May 04 13:21:22 2015] [error] [client elided] PHP Fatal error: Call to undefined function filter_var() in /…pathto…/vhosts/myhost.com/wp-content/plugins/js_composer/include/classes/shortcodes/shortcodes.php on line 290
I’ve uninstalled it for now but the theme is just limping along.
What a disastrous update, all in all. More coffee is needed over there in WP land.
