In reference to the following existing question. Wordpress Plugin : Can't process Indexing Queue I was unable to participate in the comments due to having a new account and less than 50 reputation.
I am having a problem getting the Algolia WordPress plugin to process the index. Running the latest version of WP and just downwloaded the WP Plugin from Algolia today. When I run WP_DEBUG and WP_DEBUG_LOG in my wp-config file I get the following output on any WP back end page.
has_cap was called with an argument that is deprecated since version 2.0.0! Usage of user levels by plugins and themes is deprecated. Use roles and capabilities instead. in /var/www/html/dealer/wp-includes/functions.php on line 3890
Line 3890 in wp-includes/functions.php just references the code that generated the error.
trigger_error( sprintf( __('%1$s was called with an argument that is <strong>deprecated</strong> since version %2$s! %3$s'), $function, $version, $message ) );
This appears to be an unrelated issue.
I should point out that this is a dev test server running locally on our internal network. I'm starting to wonder if that's causing the issue. I installed the same plugin on our live version of the site and everything works as expected.
We have never noticed any logs related to user capabilities. Your best bet to remove those notices is to:
Please ensure that all the requirements are met: https://community.algolia.com/wordpress/installation.html
Do you have any errors logged on the "Logs" page of the Algolia plugin? Might be useful to also give us the list of plugins you are using.
