Undefined index: piwik_pro_ads_enabled

Just FYI I will mark it already as resolved as we have created a patch that should prevent this particular issue in the future (in https://github.com/matomo-org/matomo/pull/17233 ). However, be great if you could still reply to do the above question as it’s not clear why this would show an error in the first place.

Thanks for this @denisit71

I’m assuming there’s maybe some typo like a bracket not correctly set etc. You could remove some lines and make this function around line 118 look like this:

    public static function isAdsEnabledInConfig($configGeneralSection)
    {
        $oldSettingValue = false;
        $newSettingValue = @$configGeneralSection['piwik_professional_support_ads_enabled'];
        return (bool) ($newSettingValue || $oldSettingValue);
    }

or even

    public static function isAdsEnabledInConfig($configGeneralSection)
    {
        return true;
    }

Does this help @denisit71 ?

Thanks for this @denisit71

Any chance you could post your system report see https://matomo.org/faq/wordpress/how-do-i-find-and-copy-the-system-report-in-matomo-for-wordpress/ ? The report should be anonymised automatically. Alternatively, you could email this to [email protected] .

These notices/warnings should all be suppressed and not shown. There is likely some PHP setting that forces these messages to show up. Maybe some plugin overwrites the error reporting level and the system report would hopefully help us reproduce this issue. Thanks for this.

Glad you found it @denisit71 . Thanks for finding this out and reaching out to them. Very appreciated.
