Thank you very much * I copy “object-cache.php file (size : 4KB)” and I paste this to /wp=content/. and then i purge all cache, and I checked again /wp-content/. * object-cache.php file (size : 4kb) automatically changed to object-cache.php file (Size : 80kb; redis object-cache file). so the problem is not solved. * before completely removing this plugin. I just wanna ask if this redis plugin works fine though it is not drop-in w3 total cache. * my little thought, I guess my hosting(cloudways) manages the Redis plug-in, and I wonder if this redis plug-in works well in this state anyway. Even if it was not completely linked to the w3 plug-in. * cause I’m not confident solving the problem after I delete and re-install w3 total plugin. ( my other 2-3 sites has the exact same issues so i guess re-installing’s not gonna work….) * If this object-caching is okay with functioning and okay with being managed by cloudways server side, please tell me. I can ignore the drop-in warning sign. * If object cache function is not working, I would try deleting and following what you said * * For your information, in diagonostic section’s drop-ins info : * ``` Ignored Groups: [ "counts", "plugins", "themes", "wordfence", "wordfence-ls" ] ``` * Drop-ins: [ “advanced-cache.php v by “, “db.php v by “, “Redis Object Cache Drop-In v2.0.21 by Till Krüss” ] * * Redis Overview (though, drop-in warning sign shows up) : Client: PhpRedis ( v5.3.4) Drop-in: Valid Key Prefix: wffanywzsn Connection Status: Connected Host: 127.0.0.1 Port: 6379 Database: 0 Connection Timeout: 1s Read Timeout: 1s Redis Version: 5.0.3 * Forum: [Plugins](https://wordpress.org/support/forum/plugins-and-hacks/) In reply to: [[W3 Total Cache] object cache plugin (redis)](https://wordpress.org/support/topic/object-cache-plugin-redis/) * Thread Starter [benlee](https://wordpress.org/support/users/benlee/) * (@benlee) * [4 years, 7 months ago](https://wordpress.org/support/topic/object-cache-plugin-redis/#post-15083217) * Thanks for replying. I did what you said. But the problem persist. * So, I re-checked if object-cach.php (Just deleted from /wp-content/) is exist. * I regenerated again, So the problem persist. * Should i move this file to /plugin/w3-totalcache/wp-content/ ? * There’s 2 object-cache.php files 1. /wp-content/ 2. /wp-content/plugin/w3-totalcache/ wp-content/ * Forum: [Plugins](https://wordpress.org/support/forum/plugins-and-hacks/) In reply to: [[Autoptimize] minification problem with checkout-button](https://wordpress.org/support/topic/minification-problem-with-checkout-button/) * Thread Starter [benlee](https://wordpress.org/support/users/benlee/) * (@benlee) * [4 years, 7 months ago](https://wordpress.org/support/topic/minification-problem-with-checkout-button/#post-15062388) * yes, you’re right. it doesn’t show up after diabling optimizing plugin. * I was embarrased that i assume it is because of wp rockt + autoptimize plugin. * that’s was the only changing part, so. * Thanks for the super fast reply. maybe I should ask for the theme provider. have a great day !
