White Screen After Most Recent Ajax Search Pro Update

[DaveNParticipant]

Hi Ernest,

Since the recent Ajax Search update, we seem to be getting these errors (which, bizarrely seem to come from RPP). We get white screen when we go to appearance-customize and these errors appear

[02-Nov-2018 18:32:35 UTC] PHP Warning: array_diff(): Argument #1 is not an array in /home/newsoutheastasia/public_html/wp-content/plugins/related-posts-pro/includes/related_content.class.php on line 1159

Any idea what could be going on?

Thanks in advance for your help

Hi!

Not sure, those does not seem to be related to the search. I have checked the code part, but it is not shared within the two plugins. These should not cause a white screen either, as those are only warning messages, not fatal error reports.

Anyways, I have quick-fixed these issues on a test server. Can you please try replacing one of the files:

1. Open up the wp-content/plugins/related-posts-pro/includes/related_content.class.php file on your server
2. Replace it’s content with this
3. Save the file

The error reports should go away.

Best,

Hi Ernest,

Thank you very much for that. I have made that change. I’m afraid I’ve found more issues re RPP errors, on product pages. These are showing

Hi!

Thank you for reporting these as well.

I have made another patch of these notices. Please replace the same file with this. Let me know if you still get any errors.

Best,

Thanks again Ernest!

Hi again Ernest,

Sorry to bother you again. I’m afraid the messages have come back.
These are on product pages where the second instance of the plugin is showing. On normal posts, everything’s fine. The errors now read

Hi,

These seem like the exact same errors as before, from the original file. Can you please make sure, that the file is replaced with this code, as I earlier suggested? Thank you!

Best,
Ernest Marcinko

Hi Ernest,

Sorry! I don’t know what could have happened there. I asked my hosts to swap that code. I’m sure they had done, because the error disappeared for a while. I’ll ask them to do it again.

Thanks!
