Cache-Enabler Plugin Cache is not created or served

Hi,

I have been using Centminmod for my server for a few months. Last night, I just did an update for Cache Enabler and Centmin code.

---

However, after these update, Cache Enabler did not create any cache. Before the update, according to documentation of Centmin, I can check whether I have cache serve by looking for the x-handler: wp and/or html timestamp. And I am sure that my site did serve the cache. As for now, no cache is created and served. I saw php running exhaustedly.

Please help. I am a tech guy, so I don't know where to fix.

Thanks.

 

The last time of cmupdate is probably 3rd Feb before my last night update, according to running the code from this Beta Branch - update centmin.sh menu option 22 wpsecure include file template in 123.09beta01.

Code:

Thanks, I just updated my output.

 

Ah, no, I never use auto minify both on cloudflare and cache enabler.

More info: the cache hasn't been generated, after the update.

I also did this part when update:

Code:

- Existing cache enabler wordpress site users will first update 123.09beta01 local code via cmupdate command and then run once centmin.sh menu which will now auto detect all of your wordpress cache enabler enabled sites to see if their respective generated include files have the latest configuration update in /usr/local/nginx/conf/wpincludes/${vhostname}/wpcacheenabler_${vhostname}.conf where ${vhostname} is your wordpress domain name

I notice these 2:

Code:

#########################################################################

Code:

Cache entry deserialization failed, entry ignored
Cache entry deserialization failed, entry ignored

Is it considered updated successfully?

I also notice this happens when comparing 2 of my site:

Site 1: is the newly update cmupdate & cache enabler 1.5.1
- No cache-enabler folder in wp-content, no cache-enabler-advcache-domain.json

Site 2: not updated to new cmupdate & cache enabler is 1.4.9
- Have cache-enabler folder in wp-content and cache-enabler-advcache-domain.json

Is it the problem?

 

Code:

ce_count=1 updated: mydomain.com

Is the one with the cache enabler issue.

I did the wp-cli de/reactivate, output is still the same. Nothing changes.

 

yes i did, still nothing changes

 

I updated, but still no changes ...

 

Is there anyway to downgrade both centmin and cache-enabler to my previous version? I just need working cache again.
