[Resolved] Flickering sidebars and pages

[Halil]

Hi,
I have a long lasting flickering problem. When I hit Home button, sometimes whole page,navigation menu, top social menu etc flickers.

When I hit my logo same issue again. When I click some button on navigation menu page flickers.

I couldnt remove it no matter what I did. Really frustrating issue for me. I have setup many other sites many times just to isolate the reason but no luck. Only thing that I have found is that, if I remove newsletter subscription widget from sidebar it just flickers less. But not gone completely.

Tried with different laptops, same issue.

I have disables many css codes, tried everything that I am capable of.

Here is a recording what It looks like https://youtu.be/lZKdyRMEWHM
Would u pls have a look at it?

Hi there,

Some sort of caching issue I believe.

Have you tried disabling Nginx-Helper?

If not then try disabling all plugins to test.

Let me know 🙂

[Halil]

it is definitely not Leo, tried with cache, without cache, without only a few plugins enabled (which are must have ones for my blog).

U may remember the very same issue a year ago too. Never gone, just diminished a bit, but it is now really very annoying thing for me.
Thanks for your quick response.

Then I’m not really sure what we can do to help?

From my experience, problems like these are because of caching (where the CSS is loaded etc).

You can test any of our sites in the site library and shouldn’t be any issues like this:

I started with a child theme of GP every time, without nothing everything seems OK. As soon as I add a few plugins it starts flickering. Shortcodes Ultimate and Mailchimp for WordPress are essential plugins for me, there are no other fancy things and the design is not complicated, just played with settings in the customizer.

I appreciate if u may look into it as an admin, I may provide passwd/user. If not, that’s fine too. I know ppl here are very quick in helping and to the point, I saw this since I started using GPm for almost 2 years.

If I cannot solve it, I have to try another theme unfortunately.
Thanks a lot.

So that is basically saying that a third party plugin is causing this and unfortunately there isn’t a way for me to tell (even as an admin) which one is causing it without disabling them.

Perhaps the best way would be to duplicate the current environment on a staging site so you can go through the debugging tips and identify the cause?

[Halil]

I have created many other staging sites with the same settings and ended up with the same flickering issue unfortunately. Annoying part is that I am not able to isolate the reason. Just 2 plugins, some php codes which Tom or you gave me for some other settings, that’s all.

Anyway, thanks a lot.

I have created many other staging sites with the same settings and ended up with the same flickering issue unfortunately.

So you mentioned that the issue doesn’t exist without any plugins activated. When you set up the staging sites, were you able to identify which one is causing the problem by activating them one by one?

That is really the first step to debug this kind of issues.

[Halil]

Half Shortcode Ultimate and mostly Mailchimp for WordPress, both are very widely used (at leats it seems so) , I am using paid versions.

There is also the caching plugin and this:

I know, but with this plugin disabled I am having the same issue too. It just locally loads Google analytics code.

Usual suspects are the two plugins I mentinoed above, or my css codes, or my php codes (which I am not capable of writing on my own)

[Leo]

It just looks like something is making CSS to load in the footer instead of header.

And honestly, I’ve seen this from time to time and cannot recall a case which isn’t caused by caching.

If you are willing to setup a staging site, disable all plugins, make sure the issue no longer exists, then enable the plugins one by one to identify the issue, we can then try to help.

I really don’t see any other ways to solve it.

Thanks for your understanding 🙂

[Halil]

I’ll try it one last time and let u know. thanks.

[Leo]

Sounds good 🙂

Hi again,
I have created another site and trying to figure it out for hours.

There is nothing wrong with Ultimate Shortcode plugin, I have tested it without any issue.

However, if I put some widgets into sidebar, like Custom HTML or Mailchimp subscription plugin widget it starts flickering badly. The one in the site now is a custom html code taken from Mailchimp.com.

Pls check the video again, very heavy flickering.

New staging site https://analitik.istanbul
I dont know whether it is related or not, there is only below php code in my functions.php, which Tom or you gave me a year ago. and here it is

/*remove commas between categories*/
add_filter( ‘generate_category_list_output’, ‘tu_remove_category_commas’ );
function tu_remove_category_commas() {
$categories_list = get_the_category_list( ‘ ‘ );
return sprintf( ‘<span class=”cat-links”><span class=”screen-reader-text”>%1$s </span>%2$s</span>’, // WPCS: XSS ok, sanitization ok.
esc_html_x( ‘Categories’, ‘Used before category names.’, ‘generatepress’ ),
$categories_list
);
}
