Help needed with configuring memcached (B.O crashes with it enabled)

[Ray UK]

Hi, I'm currently running 1.7.8.1 and trying to get memcached running properly.

I'm using PHP 7.4 and have installed memcached.

However, when I set the file handler on the server to memcached (instead of files), the front office does speed up quite a lot, but...

The back office crashes on all pages except for:
Dashboard
Shopping Carts
Attributes & Features
Discounts
Customer Service & Merchandise Returns
Stats
Image Settings
Carriers
Search

These pages all show the message "The page isn’t redirecting properly".

Is anybody able to help with this.

Thanks

Does anybody have any ideas for this issue ?

 

Or is there a comprehensive list somewhere of which php extension should be installed, and how they are configured to make the best of prestashop.

Should the like of pagespeed, opcache, memcached etc all be running? And should the prestashop caching system also be running alongside the php extensions.

Ive not found any site that explains what should, and what shouldnt, be installed.

 

When I installed memcached I followed guides online. A lot say set the session handler as memcached (instead of files) but doing this causes pages in the b.o to not load up.
If I leave the session handler as "files", the save path is stated as "/var/cpanel/php/sessions/ea-php74" but no files seem to be created in there.

 

If somebody has created a guide for setting up "easy apache" for use with prestashop that would be really helpful for a lot of people.

Cheers for any help

Ok so Ive installed APCu 5.1.21 and switched to that in the PS config.

The site loads quite a bit faster and getting 95% on GT metrix and Google page speed tests.

The main thing lowering the score is not the css files as they are not deferred. 

Where has the option gone to move css/js to the bottom of the page?
