Long wait time when saving blog item

Hi! It's my first post here and unfortunately I have to write new topic in "Support".

Anyway - I've got some problems with my site. It's running on latest stable version (1.6.5) on Quark Open Publishing theme, all default plugin (while GitSync is turned off) and some additional ones (like Advanced Cache, YouTube). While saving blog item (especially when it's published) wait time is very long (like few minutes) and sometimes I'm getting time out error from server side. Below you can find screenshot from such situation:

I've checked the Apache's error logs and I found such thing for similiar situation:

Any ideas what can cause such situation and how to solve such question?

Hi @bwanot, I am not sure (Git Sync adds a noticeable delay but if it is disabled it should not be triggered on Page Saves). Perhaps change the theme to the standard "Quark" and see if this behavior is still present?

Hi @paulhibbitts, thanks for the reply. Well, my website is on "My Theme" to be exact and I made some changes in twigs and styles, so I'm affraid that changing theme when site is live is rather a bad idea from my perspective ;)
Such long wait time is visible especially on long articles and when they are published. Short ones and unpublished don't behave that way.

Hmm... the wait time you describe is not usual - I would either try disabling plugins (esp Advanced Cache) to see if that changes things. If it is your production site it might be worth doing another fresh Grav install on the same server and then try out your theme customizations there etc.

@paulhibbitts Well, I turned off the Advanced cache plugin and still the problem occurs. What's more - now I'm getting timeout error after 5 minutes of waiting for server. Such situation occurs when I'm trying to save this long article https://geekretro.pl/jak-kupowac-gry-w-japonskim-nintendo-eshop .

By the way, got one question. Why there is a 303 redirect for ../admin/pages/jak-kupowac-gry-w-japonskim-nintendo-eshop which takes 3-5 minutes of waiting (TTFB) or timeout request and after that there is status 200 code for ../admin/pages/blog/jak-kupowac-gry-w-japonskim-nintendo-eshop ? Maybe this 303 is a problem? (Sorry if this question is stupid, but I'm not a developer ;) )

And here is my PHP settings from DirectAdmin (maybe there should I turn on/off some options?):

Any ideas?

Making a fresh install is a good idea, but recently don't have enough free time to do it 😕

I think I found the source of my problems. Need to test it in 100% but I think that one particular plugin was messing around with my site - TNT Search. I have turned it off (since I'm not using it) and now every save of long article is fast as it should be.

Hi @bwanot, glad you might have tracked down the issue! I use the TNTSearch Plugin myself but perhaps there was an issue with the particular config etc?

Re: PHP settings, you can see Grav's recommended ones at https://learn.getgrav.org/16/basics/requirements#php-requirements

Could be, who knows. Well, the good thing is that CMS is working fine 🙂 As for PHP settings I've tried to set it as manual says few weeks ago. Hope that everything will be working great. Thanks for your help.
