I think I found the issue. The error is being triggered by the plugin that is looking for the lrc_admin_notice function in the WordPress admin_notices filter. However, WordPress isn’t passing any. So I edited line 430 on the following file:
/wp-content/plugins/repayment-calculator/settings.php to this:
function lrc_admin_notice($message = '') {if (!empty( $message)) echo '<div class="updated"><p>'.$message.'</p></div>';}
Basically assinging a blank value.
Below is my server setup:
WordPress version 6.7.1
Current theme: Hello Elementor (version 3.2.1)
Current plugin: Loan Calculator (version 1.3)
PHP version 8.2.27
