1. I've also made some tests such as deativating plugins, change theme to twenty sixteen, but I cloudn't conclude how to solve my problem. The admin and public site was slow anyway.
Does that mean, even without Toolset or WPML the site is slow?
This is important to know.
It is elaborated specially in the WPML performance DOC to test this as well.
2. What I noticed is that ACF Gallery Field drag and drop feature works when I deactivate the AVADA theme and activate the twenty sixteen theme.
This needs a new ticket
As it seems this is not even related to Toolset, if I understand correctly?
Also all other issues require new Tickets, I apologize this
I see your site loads in 3,xx seconds, 180 Queries, nothing unusual here.
This can be expected with WPML and WordPress.
(backend)
Front end is a bit more concerning, 512 Queries and almost 5 seconds.
(as admin)
3. Your wp-config.php presents customized details.
One of them is weird:
// ACF Disable automatic updates check. It slows down WP Admin by 30sec. It cannot contact update servers. Comment this in the future to reactivate auto update feature
//define("OTGS_DISABLE_AUTO_UPDATES", true);
This has nothing to do with ACF, it's our own Update path.
Also, if your server rejects our URL paths, it may reject many other things and be the reasons for the slow down.
Some other customizations will probably conflict with CRED; when it comes to uploads.
4. W3TC is not set up on this site, otherwise wp-config.php would present it's rules:
hidden link
5. Disabling all Plugins, this error happens:
Fatal error: Call to undefined function acf_form_head() in /home/abbeyinmo/public_html_project/wp-content/themes/abbey/functions.php on line 393
6. You have a Theme "Abbey" running, but use Toolset layouts + AVADA integration.
Is this CHILD of AVADA working fine with the integration?
7. Reenabling Plugins, took a while.
This without having WPML or Toolset active at all.
Each plugin activation loads seconds over seconds.
(Front End is remarkably faster though without any Plugins at all)
8. It seems to me your Server is not properly configured. Activating many plugins a time (to stress execution time) returned a E 500 being clear that this is a Server timeout.
9. having reactivated all Plugins, I got the site down to 3 seconds on front end as logged user.
10. Disabling only WPML, split down the Queries to half but load time jumps up to 5 time as long.
Are you using some hardcoded calls to WPML functions, that are not wrapped in conditionals, to check if the plugin is active?
11. Additionally deactivating all Toolset Plugins, brought it down to a very acceptable speed of less then a second.
12. Reactivating only WPML Plugins bought it up back to 3.5 seconds, (which is expected with WPML)
13. Locating the culprit here was then easy:
- One part is WPML, please open a ticket with the Support of WPMl and follow their instructions
- The Other, generating never 300 queries and 1.5 seconds load time only is Views.
You load 2 quiet big Parametric Searches on the Home.
The Views not only query 300+ posts with lots of Queries but also include relative much HTML conditionals.
This can be the reason this is so slow.
I could escalate it to the DEV for analyzation but I can not promise any fast solution, as it is at least partially expected what is happening here.
Additionally I see slow Queries (and those are the only one reported) by another Plugin along with Views:
Fusion Core.
And Views is, as suspected, slow due to the numerous Filters and conditionals, you can see that in the Query reports.
So, to summarize, I personally would suggest to change some setups here, as this will not bring much improvement with Cache or similar as you want a Parametric Search to be uncached of course.
Additionally, Cache is automatically turned off for Views when:
WPML is active, since the same View can produce different results for different languages.
https://toolset.com/documentation/user-guides/how-to-use-views-parametric-search-on-large-sites/
So, you can not any way use Views cache.
Also with as many conditionals and queries, it is expected to slow down the process.
I am not saying we can not improve.
I will if you request, involve the DEV here.
Please let me know your findings and if you agree.
If I escalate I will need a way more minimal Site, no Plugins but Toolset and WPML, to provide to the DEV.
Can you provide me a snapshot of such a site ?
Thanks for your patience and understating in this.
