Plugin updates fail

Trying to update child plugins from the dashboard, they all fail - showing a red cross, but no error shows up.
Resynced, didn’t help.
Went to the status/error logs, the only line i saw that could be related is this:

PHP Warning: mysqli_num_rows() expects parameter 1 to be mysqli_result, bool given in /home/customer/www/ on line 273

@amaau looking at your system reports from your other ticket your MainWP system looks to be ok.

The Child Site is not returning the correct response and is returning False.

Can you post your Child Sites system report ( you may redact site URLs if you feel it important )

Thanks for the reply Keith
Forgive the dumb question, but where do I find a child site’s system report?


Child Site > Settings > MainWP Child > System Information > Blue Button

Redact any personal URLS before uploading please. If we need more info I will have you open an Official MainWP support ticket instead.

Thanks, here -

@amaau Yeah I am not seeing anything jump out in these logs that would cause this.

You might want to turn on WP-Debug on the Child site to see if there is anything generated during updates.

You are connected too… Only thing we can do now is tried and true Process of Elimination.
Start with disabling your Security Plugins.
Then the theme.

Would you mind opening a private Help Desk ticket as well so we can collect some additional information & investigate further?

I have to solve something else first,
will get back to you on that if it’s still an issue
Thank you
