Best regards.

Hello Sa?a.

Thank you for reply. If I right, problem is with apache_response_headers which does not work properly in PHP 7.x. I am using PHP 7.x, but my site is not on Apache.

Could you please send me exact PHP code?

Thank you.

Hello

I’m glad I could help. I am looking forward to see updated of your plugin.

Best regards.

When I activate debud log, it fills debug log, after several minutes it is 3MB, and it is reseted to zero. I can rise up debug file size, but that is not solution. I am trying for days to figure it out, (you can see my config above), no metter what I do, I can not find URL which is cached more than several hours ago.

Site speed is 3-4 times higher/worse (according to crawl statistics inside webmaster search console) than it was before while using another WP caching plugin.

I think I will delete LSCache and get back to previous plugin.

And like this:

Hello

I turned on debug log, after it started to fill quickly (more than 2MB).
I searched inside that file for “Purge” and I found 25 results, for example:

But, I don’t know what it means, aldought, I think that “get_uid: 322” is maybe ID of logged in user (Contributor role)

Hello.

About Do Not Cache Roles setting.
Yes, I do not wish that any url is cached for logged in user. Just administrator is logged in, and also I have option on site for visitors to register and login, they can register and login as “contributor” role.

When I am (or any other user) logged in nothing is cached because of Do Not Cache Roles setting, and when any user is logged in this is in HTTP headers:
x-litespeed-cache-control:no-cache

Also, I am sure that I am not logged in when checking cache status.
For example, after I logout I visit some URL, and I have this in HTTP Headers:
x-litespeed-cache:miss
after I refresh that same URL I have:
x-litespeed-cache:hit

Problem is that after some time (from few to several hours) practically all cache is purged, and it is also purged after I publish new posts.

How to tell to LSCache to keep cached pages in cache until TTL expire?

Hello again.

Maybe you should look at this too, I have this in error_log in: /wp-admin/ folder

Hello

Yes, that was my thought too. I can’t know on which of images is that (I have many images on site), I will try to find it, if I can.

I would advide you to make something which will deal even with ivalid values, for example, in this case, to check first if value is 0, and if it is, to do nothing (not to process further). Also, you should predict invalid values for all other fields, sometimes is even useful to predict “impossible” values. There is a lot of cheap cameras and cellphones on market, so you can not trust all of them that they will write only valid/standard info in EXIF data.

If you have any question do not hesitate to ask.

Best regards.

It is not working.
I put your code into functions.php inside my theme folder. After that, when I upload new image to post, and if I wish to edit that image using built in WP image editor, I can not see that image, just blank place where image should be, and I get this error:

“Could not load the preview image. Please reload the page and try again.”

I can not edit original image, to see if this your code then do what it should, to replace/delete original image.

Will that remove sticky option from posts, or it will just list sticky posts? I need to “unsticky posts”.

Hi.

Yes, that is probably added by one plugin which read EXIF info from images, and if there is EXIF GEO (GPS location of place where image is taken) to show image map.

About 0.3% posts have image with GPS info, so for most posts that is not needed, just one line more of not used code in HTML.

After I change file name of uploaded image to WordPress using linux bash, how to update image URL in WordPress database?

Yes, you are right. Function above compress image using native PHP functions and GD library, which removes EXIF (that is nature of GD).

WordPress Image API uses ImageMagick if available (it is in my case), and there will be solution.
