PHP Error in admin area after update to 4.0.10

Yes, there’s a small error in the code; this notice pops up if logging is disabled.

It’s nothing dangerous, it’s easy to fix and will be fixed in version 4.0.11. You can see the Github issue page here, there’s a?solution: https://github.com/msaari/relevanssi/issues/11

Same here. Thanks.

I just updated to 4.0.10 and immediately, the wp admin displays only a blank page. I only know enough about coding to get myself in trouble. Could you please spell out where (in what file) to put the fix?

All I understand is that the fix is on the following page but not how to implement it:
https://github.com/msaari/relevanssi/commit/b9979646c74ef37b7bc45651d30d75cfb2ba4414

At this point, in order to see the wp admin area, I have had to disable Relevanssi, which is a less than optimum solution.

Thank you.

Please excuse me for appearing to reply to myself.

I took a plunge at trying to understand and went into the relevanssi files to add $content = ''; to line 29 of /plugins/relevanssi/lib/privacy.php

as per the following:

https://github.com/msaari/relevanssi/commit/b9979646c74ef37b7bc45651d30d75cfb2ba4414

I then reactivated Relevanssi. Alas. It is still causing the admin area to throw a blank page. I do not know how to find out what the exact error message is. Please advise so I can enable relevanssi again.

Thank you.

Ok, so it is slightly more dangerous than it seemed. Adding the

$content = '';

should fix the notices and warnings, though.

If you’re not running WP 4.9.6, that’ll also cause a blank admin page. That’s not good.

I’ll release a fixed version now that’ll sort out both of these issues, and then everything should work better.

Many thanks Mikko;

The update did the trick and the blank page syndrome has disappeared.
