Disabling Redis for Plugin (WP All Import) and for WP-Admin

    I’m having problems with WP All Import.

    I saw this in your FAQ:

    wp_cache_add_non_persistent_groups( array( ‘bad-actor’ ) );
    This declaration means use of wp_cache_set( ‘foo’, ‘bar’, ‘bad-actor’ ); and wp_cache_get( ‘foo’, ‘bad-actor’ ); will not use Redis, and instead fall back to WordPress’ default runtime object cache.

    Is it possible to have Redis Object Cache disabled for this plugin, so that it uses WordPress Object Cache instead?

    Is it possible to have redis object cache disabled for WordPress backend only (Wp-admin)? I ask this because caching plugins like WP Fastest Cache don’t update the statistics well with Redis active.

    Also, I tried shutting down redis server, then moving the object-cache.php file to another location, commented out the WP config settings and disabled the plugin, hopping that I would get back to the default WordPress object caching….but then I just get a blank page for every site page and for wp-admin. After bringing back the php file to the correct location all is ok again.

    My WP config settings (commented out, values replaced with xyz for privacy reasons):

    /* REDIS CACHE */
    /**
    *define( ‘WP_CACHE_KEY_SALT’, ‘XYZ’ );
    *define(‘WP_CACHE’, true);
    *$redis_server = array(
    * ‘host’ => ‘XYZ’,
    * ‘port’ => XYZ,
    * ‘auth’ => ‘XYZ’,
    *);
    */

    I’m having problems with WP All Import.

    Can you share more details on the nature of your problems?

    Is it possible to have Redis Object Cache disabled for this plugin, so that it uses WordPress Object Cache instead?

    In some ways, yes. If the calls of wp_cache_set() and wp_cache_get() specify a group, then (as the documentation indicates) you can blacklist the group to prevent the data from ever entering Redis.

    Is it possible to have redis object cache disabled for WordPress backend only (Wp-admin)?

    I think this would probably cause more problems than it would solve.

    1) When uploading a CSV file, the delimiter does not get picked up correctly. So WP All Import incorrectly sets the column header, etc… After many attempts of clearing the caches, reloading webpage, flushall redis, etc… WP All Import finally recognizes the delimiter correctly. I also notice that when importing… in Redis summoning the info command, the used memory drastically drops to near 0. Not sure if this is a problem but do find strange.

    2) Where is the documentation?

    3) Ok!

    Ok. This sounds like a problem with WP All Import, not WP Redis.

    2) Where is the documentation?

    You’d need to look through the WP All Import codebase to review its caching implementation. I don’t believe there’s documentation specific to disabling the persistent object cache for WP All Import.

    I’m not sure how they handle their support, but you could submit a support ticket and point them to this thread to give them context into the problem you’re experiencing.

    Ok, thanks for the help!

    Did you ever find a solution for this with WPAllImport?

    Flushing the object cache, Redis in this case, solved the problem. So it was a cache problem. Not sure if Memcached or the original WordPress object cache (transients) have the same problem as I only got this problem when I had Redis running.
