CPKN on "[Plugin: Popup Maker] Update & Activating 1.4.7 causes Fatal Error"

Hello,

when trying to update the plugin to 1.4.7, as soon as I activate, the page shows this error:

fatal error: call to a member function get() on null .../includes/query.php line 27

Here is line 25 to 27:

function get_query_var( $var, $default = '' ) { global $wp_query; retu $wp_query->get( $var, $default );

Not sure what's going on or how to fix it.

Any Ideas?

Note: deleted url section before "includes" for security.

@CPKN - Hmm that is way to generic for us to even know where to look. Any chance you can follow this guide and get a stacktrace pointing us in the right direction?

This is the first report of this so please bear with me and we will get it worked out.

Hello,

Thanks for the reply.

Not a problem! :-)

I will get it done ASAP!

Cheers!

@CPKN - Awesome, I am off for the night (4:30am here) so I will take a look first thing and hopefully there is enough info that I can patch tomorrow for you without any extra back and forth :).

Hello,

So had a bit of a bump getting the code to work, but then I thought I had it until I new error came up:

Fatal error: Call to undefined function nocache_headers() in .../wp-admin/admin.php on line 33

Line 33 is literally

nocache_headers()

Dunno why this affects it when adding the code but otherwise is fine?

I will try again when I can later today/tonight (currently 12:30pm), if you have any ideas on what I have done wrong, let me know.

I will keep you posted.

Note: I can remove the line of code in query.php to get my website running without WSOD, but as I am not pro with this sort of thing, I don't know if that would be bad to keep out for the long term.
