Error when logging into WordPress after installing plugin

Hi,

Does it mean that this error occurs after logging in to the back-end of the site?
Could you please provide screenshots of the plugin settings page and the error?
A simple solution: please try via the Editor of the plugin’s files, hosting file manager or ftp, in the file pdf-print.php (wp-content/plugins/pdf-print/pdf-print.php) find line 656

if ( ! in_array( get_post_type( $post ), $pdfprnt_options_array[‘use_types_posts’] ) )

and change it for

if ( ! in_array( get_post_type( $post ), $pdfprnt_options_array[‘use_types_posts’] ) && is_admin() )

Sincerely,

Hi BestWebSoft Support Team,

Thanks for your response.

Yes, the error occurs when you log in to the back-end of the website, and then doesn’t appear if you navigate around the admin area. If you log out and log back in again, the error shows again (please see screenshot 1.jpg listed below).

I tried the suggested code change, but it doesn’t seem to have made any difference to the error appearing ??

Please find screenshots available here:

Many thanks in advance for your help.

I’m having the same problem. The code change unfortunately didn’t fix it for me either. I also wouldn’t care except that I have users that have expressed concern. Thank you!

Hi,

Apologies, there was a mistake in the code, please try to change the line for the following one:

if ( ! in_array( get_post_type( $post ), $pdfprnt_options_array[‘use_types_posts’] ) || is_admin() )

Sincerely,

Hi BestWebSoft Support Team,

Thanks for your amended code update, however even after implementing the new code change, I’m still getting the same error unfortunately.

One thing I did notice: https://www.example-domain.com/wp-admin/ caused the error to trigger, however https://www.example-domain.com/wp-admin/index.php does not.

Hopefully this might be some clue into the resolution?

Many thanks,
Sara

Hi BestWebSoft Support Team,

I’ve upgraded to your latest plugin version – 1.7.3 and the same problem is still occurring.

Are there any other code changes I can make to resolve this problem?

Thanks.

The error is not gone after upgrading

Hi all,

I managed to get our wonder developer to take a look and he’s made the following change which seems to have fixed the problem:

TO RESOLVE:
Modify /wp-content/plugins/pdf-print/pdf-print.php

Find the below line (roughly line 658):
if ( ! in_array( get_post_type( $post ), $pdfprnt_options_array[‘use_types_posts’] ) )

And above it add:
if (isset ($pdfprnt_options_array[‘use_types_posts’])){

Then also add a:
}
(should be line 661) after the code:
return $content;

This problem is caused by the fact that the $pdfprnt_options_array[‘use_types_posts’] command is returning a NULL value and the second parameter of in_array is expected to be an array value.

Hope this helps!

Hi again,

We have found out the cause of the error and it will be fixed in the next update of the plugin.
