Website Strange Data Delay



I have a website I’m working on using bedrock/trellis and I’ve been noticing there is a strange delay that’s happens.

I’m using woocommerce and If I add/remove items into my shopping cart sometime they don’t show up or get removed right away.

I’m also noticing this also when I’m developing and updating php files directly on this staging site that sometimes when I refresh my browser the changes aren’t appearing.

I’ve experimented both with having the cache enabled and cache disabled. I’ve experimented with clearing the caches.

Does anyone have any experience with this and I’m not sure how to troubleshoot? I’m using wordpress 4.8.2.

My clear cache command:

ansible "web:&staging" -m command -a "composer clear-cache" -u web

My wordpress_sites.yml

branch: master
 enabled: false
 enabled: true
 provider: letsencrypt
 enabled: false


I’m willing to hire someone to troubleshoot this.

Doesn’t Jetpack include some basic caching? And you’re not using CloudFlare or anything like that?


Jetpack is disabled and I’m not using cloudfare to my knowledge.


You showed that you have caching disabled in wordpress_sites.yml; was it ever enabled? Did you reprovision your server after setting it to disabled? Deploying and provisioning are different things.


Thanks for the clarification – it was enabled – its actually enabled on my production instance which is showing the same behavior.

I may have only deployed. How do I reprovision?

cd $ECI_WORKING_DIR/trellis
ansible "web:&staging" -m command -a "composer clear-cache" -u web
ansible-playbook deploy.yml -e env=staging -e -e 'project_copy_folders=[]'


Provisioning is the “Remote Server” part of the docs, here:

The command you want is ansible-playbook server.yml -e env=<environment>

Where <environment> is “production” or “staging”.


If I provision it – will it be nuked though and then I need to go through the deploy and updating the DB process?


No, it’s safe to reprovision a live site. Try it on staging first, obviously, but you should be fine.


Interesting – I think it might have fixed it – do you normally use caching for your site in the wordpress_sites.yml? What’s the normal strategy everyone is using?


I often turn on caching. My clients don’t tend to update their content often enough, or with enough urgency, that a cache will cause an issue.


Hi – I’m still having this problem – caching is off and when I make a php file update in one of my plugins its not updating – there’s probably a 30 second - 1 minute delay and then the change appears. If someone is willing to help troubleshoot – I’m happy to pay them.


I’ve updated my nginx so it disables caching – and I’m still seeing the same problem.

~/work/websites/[master] $ curl -I
HTTP/1.1 301 Moved Permanently
Server: nginx
Date: Mon, 11 Dec 2017 19:30:30 GMT
Content-Type: text/html
Content-Length: 178
Connection: keep-alive
Last-Modified: Monday, 11-Dec-2017 19:30:30 GMT
Cache-Control: no-store, no-cache, must-revalidate, proxy-revalidate, max-age=0


Please note that you are not clearing nginx cache you are clearing COMPOSER cache, two completely different things.

I recommend NOT turning cache on for staging at all, also when you DO for production, make sure you remove woocommerce cart pages or else you will be showing users other users’ cart contents!


This is a very good tip. I wonder if this is important enough to roll into Trellis, considering how important to the WP ecosystem Woo is?

#18 has both WooCommerce and EDD examples

Maybe we should add a comment above the cache section in wordpress_sites.yml with a link to that?


Maybe. Or I could be better at reviewing the docs more often :slight_smile:
