Hi @go-sudo,

To disable the Memcached: go to BO => Configure => Advanced Parameters => Performance.

Thanks for check and feedback.

Hi @go-sudo,

It seems that your issue is not a PrestaShop's core bug but most likely a customization problem.
You should check your host.
I close the ticket, feel free to open a new one when needed.

Hi

I think you should add this on feature because it worth nothing to cache the backend (back office) of the website

Hi @go-sudo, although indeed the frontend benefits a lot more from cache capabilities than the backend, being able to use memcached for backend is still a useful feature.

So can we rephrase your feature request as "Enable PrestaShop users to choose to either use memcached for backoffice, frontoffice, or both" ?

Hi @go-sudo,
What do you think of matks comment?

[go-sudo]

Hello

I think it's good idea to give user that choice to cache the
Frontoffice
Backoffice
Both

Yes, we need to be able to specify which cache we want for FO and/or BO

[go-sudo]

I want to cache only frontoffice please

Hello any news please

[PierreRambaud]

Still not had the time to implement this feature. If you know how to do it, don't hesitate to help us :)

Still with problems with Memcached on backoffice and API/webservice, returns old values in some cases.

We need cache only on FrontOffice, how can we do that?

[PierreRambaud]

@pmartin-webimpacto Not implemented yet, as far as I know. Ping @khouloudbelguith if you know how to implement Memcached only for frontend?

Hi,
let me notice that on prestashop 1.7.5.2 this is a huge issue with caching on the backend. I'm trying to change product SEO URLs and with memcached enable although the product saves the new URL, cache is not invalidated. Thus the product URL stays the same as before.

So my use case is this:

• Enable memcahed
• Edit a product in backend
• Change the SEO url
• Save the product
• In the JSON Response I can see the URL indeed changed
• Refresh the page
• The old URL appears instead of the new one.

So basically the real bug is that cache is not invalidated after certain actions. It's not a terrible idea to cache the backend but you need proper invalidation mechanisms. Otherwise it's best not to cache the backend or the user would undo his changes.

Now the second bug.

The clear cache button in performance options doesnt' seem to correctly flush memcache cache. In the same example as before I cleared cache multiple times but nothing happened.

I disabled the cache option for memcache and immediately I saw my changes reflect in the backend.

I think this issue needs real attention as it'snot a feature request but a real bug affecting administrators.
