Title: Website not updated when database changes Last modified: August 18, 2016 --- # Website not updated when database changes * [lawtai](https://wordpress.org/support/users/lawtai/) * (@lawtai) * [20 years, 4 months ago](https://wordpress.org/support/topic/website-not-updated-when-database-changes/) * I went into the database to manually change my user description. However, I noticed that the setting isn’t being changed by the webpage itself. If I go in through WP to change it in the admin, then the user description gets updated. This is a problem for me as I’m updating html code which gets parsed to characters when I update through the admin panel. * Is there a reason why making changes in the database doesn’t immediately reflect on the webpage itself?

You can disable caching( temporarily or permanently) by adding this line to your wp-config.php * `define('DISABLE_CACHE', true);` * Thread Starter [lawtai](https://wordpress.org/support/users/lawtai/) * (@lawtai) * [20 years, 4 months ago](https://wordpress.org/support/topic/website-not-updated-when-database-changes/#post-311199) * thanks, that did the trick! Do you know how long it caches for before updating again? * [vkaryl](https://wordpress.org/support/users/vkaryl/) * (@vkaryl) * [20 years, 4 months ago](https://wordpress.org/support/topic/website-not-updated-when-database-changes/#post-311201) * Hey, Kafkaesquí – how do you make it permanently disabled? * Thread Starter [lawtai](https://wordpress.org/support/users/lawtai/) * (@lawtai) * [20 years, 4 months ago](https://wordpress.org/support/topic/website-not-updated-when-database-changes/#post-311210) * I would think you’d just leave that line in your wp-config.php permanently * [vkaryl](https://wordpress.org/support/users/vkaryl/) * (@vkaryl) * [20 years, 4 months ago](https://wordpress.org/support/topic/website-not-updated-when-database-changes/#post-311213) * As opposed to messing about with the wp-config.php file on a daily basis? Oy. Sheesh. * Okay. It can just live there forever. As I posted somewhere else, why do I need a cache anyway? * [Kafkaesqui](https://wordpress.org/support/users/kafkaesqui/) * (@kafkaesqui) * [20 years, 4 months ago](https://wordpress.org/support/topic/website-not-updated-when-database-changes/#post-311223) * lawtai, last I checked the cache is updated either once a day or by specific WP events. However, there is a PHP constant for expiration time on the cache you can set: * `define('CACHE_EXPIRATION_TIME', 86400);` * Time value is in seconds. Set to whatever is desired (although a value of 1 is probably self-defeating). * vkaryl, WP 2.0 offers a wp_cache_flush() function, so there’s nothing stopping some plugin developer with free time from adding a little button in the admin pages which clears it. Oh, for some free time! * [vkaryl](https://wordpress.org/support/users/vkaryl/) * (@vkaryl) * [20 years, 4 months ago](https://wordpress.org/support/topic/website-not-updated-when-database-changes/#post-311227) * *laughing* Heh – free time? What’s THAT? Okay – that would be nice…. but I’m not by any means capable of producing it…. so I’ll either add in the exp time line or just leave it permanently disabled – as I said, why do I need it anyway?( The cache, I mean….) * [Kafkaesqui](https://wordpress.org/support/users/kafkaesqui/) * (@kafkaesqui) * [20 years, 4 months ago](https://wordpress.org/support/topic/website-not-updated-when-database-changes/#post-311230) * On busy sites it can aid in response times, since a cached, static document residing on the server can be retrieved a lot quicker than a PHP document performing a bunch of sql queries and whatnot. It’s all about speed. Well, speed and load. * [vkaryl](https://wordpress.org/support/users/vkaryl/) * (@vkaryl) * [20 years, 4 months ago](https://wordpress.org/support/topic/website-not-updated-when-database-changes/#post-311236) * Oh. Heh. Well, no WONDER I don’t need it then…. *laughing* * [Kafkaesqui](https://wordpress.org/support/users/kafkaesqui/) * (@kafkaesqui) * [20 years, 4 months ago](https://wordpress.org/support/topic/website-not-updated-when-database-changes/#post-311241) * Even on let us say “leisurely” sites it can provide some improvement. But that’s up to the admin to decide… * [vkaryl](https://wordpress.org/support/users/vkaryl/) * (@vkaryl) * [20 years, 4 months ago](https://wordpress.org/support/topic/website-not-updated-when-database-changes/#post-311244) * Oh, WHAT a kind man you are tonight! Tell you what though, I think I’ll just do my “leisurely” thing until some wonderful plugin programmer produces that nifty li’l button…. * Viper – you out there, buddy? Listening? * [richards1052](https://wordpress.org/support/users/richards1052/) * (@richards1052) * [20 years, 4 months ago](https://wordpress.org/support/topic/website-not-updated-when-database-changes/#post-311305) * I love the idea of speeded up response time through using the new cache system. But in some cases, it’s taking me 20-30 minutes before I can see edited posts display the material I’ve added to them. This just doesn’t work for me. * > last I checked the cache is updated either once a day or by specific WP events. * Would a “specific event” include publishing or republishing a post or publishing or deleting a comment? If so, perhaps the cache isn’t working properly in my case or there’s a bug in it since as I say I’m not seeing newly edited material. * I think I’ll have to disable the cache as well. Can Kafkaesqui or someone tell me whereabouts in the config.php file I’d place that code? * BTW, before upgrading to 2.0 I had wp-cache plugin installed until it started doing the same weird things (not allowing me to clear my cache & see updated web posts & web pgs.). I’m guessing that there must be operational similarities between the new wp cache & wp-cache. * Is there any way I can continue to use the cache but set the expiration time to a short enough time frame that it would allow me to see newly edited pgs? * [Kafkaesqui](https://wordpress.org/support/users/kafkaesqui/) * (@kafkaesqui) * [20 years, 4 months ago](https://wordpress.org/support/topic/website-not-updated-when-database-changes/#post-311442) * When editing wp-config.php, place any of the suggested additions anywhere before this line: * `require_once(ABSPATH.'wp-settings.php');` * Yes, events which should update the cache include publishing posts. However, I’m not educated enough on the built-in cache functionality to say right now which events update what, and what exactly is being cached. * For defining `CACHE_EXPIRATION_TIME` you could try a few minutes or so, 120-180 seconds. Even that should provide a small benefit over non-caching (on busy sites). But again, as I’ve not completely investigated this feature of 2.0 I can’t say all of what is affected by `CACHE_EXPIRATION_TIME`, or if it will help in your case. * [richards1052](https://wordpress.org/support/users/richards1052/) * (@richards1052) * [20 years, 4 months ago](https://wordpress.org/support/topic/website-not-updated-when-database-changes/#post-311544) * Sorry if I appear dense (I just want to understand clearly what will happen) but, if I set that expiration duration that means that if the cache doesn’t clear itself immeidately & automatically ( as I believe it should) then within say 120 seconds I will definitely be able to see the changes to the post? * Or did I miss something? * [gpaulson](https://wordpress.org/support/users/gpaulson/) * (@gpaulson) * [20 years, 4 months ago](https://wordpress.org/support/topic/website-not-updated-when-database-changes/#post-311634) * I have just installed the cache-flush plugin ( [http://www.xyooj.com/blog/plink/technical/31/plugin-to-flush-wordpress-cache/](http://www.xyooj.com/blog/plink/technical/31/plugin-to-flush-wordpress-cache/)) because I was having problems when I edited posts it would pull up the cached version for me to edit instead of the version with the changes I had just made. * Kind of a pain to have to go ‘hit the button’ but much easier than going in and manually deleting the cache files. * My other wish is that the cache directory was not placed in the ‘wp-content’ directory since wp-content contains the files that should be backed up regularly and there is no need to backup the cache. Too bad it was not placed in a wp-cache directory at the same level as wp-content.
