Hello Ismael,
thank you for the answer.
Because we are working on this page during these days – I had to find any solution for problem.
Finally I found something in old threads. It seems to be OK for us.
I have my result – low header (without logo) on wide and narrow screens, without changing to mobile menu (burger), sticky to the top of window.
I have added lines to Quick CSS in
Enfold Theme Options/General Styling/Quick CSS

#header_main .container, .main_menu ul:first-child > li a {
height: 25px !important;
line-height: 30px !important;
}

@media only screen and (max-width: 767px) {
.responsive #top .av-main-nav .menu-item-avia-special {
display: none;
}
.responsive #top .av-main-nav .menu-item {
display: block;
}}

@media only screen and (max-width: 767px) {
.responsive #header_main .container {
position: fixed !important;
}}

The page is already in use but I can not share a link unfortunately.
If the CSS lines are fine – let’s close the thread.
Thank you for help.
best regards
Jakub

Hi Rikard,
so in private content login deatails.
Enter WP panel, open Mobile SCANMED Systems (main) page for editing, it is even not neccecery to change or add anything, then press UPDATE and you should see what I see: white screen with warnings/informations.
Some pages of this site does not generate this problem. I suppose it depends on higher content.

best regards
Jakub

Hi Rikard,
it’s complicated – it happens when I work with back end od my site, after pressing Update button. It’s visible only for me. You should be a user of admin panel of this site. Dou you practice such thing?
We think it could be errors in few files of themplate and we maybe can change them on serwer using original files from Enfold instalation set.
best regards

Hi Peter
Thank you for explanation. I think I will try this solution.
But I am still courious why the changes in *.po file are inevective. It seems to me quite comfortable solution to edit *.po and upload it via ftp.
But there is no effect of this activity. I think theme doesn’t know it shoud use this PL.po
As I know – there is only one place where I have checked the polish language of website – the main settings in WP panel. Is it enough?

And one more thing – as I see – in this code there is a specifically indicated the area where we want to make some changes. Here – in avf_form_autorespondermessage ($message)
If I would like to make some changes in different areas – I would have to correctly indicate the right section of code. Am I right?

best regards
Jakub

Hi Victoria
I use poedit – maybe here is the problem.
The look of the content is different.

Thank you and sorry – I am not a programmer and I have some problems with this technical things.
Your image you have sent me – is it *.po file?
In what kind of application?

best regards
Jakub

Maybe my Enfold doesn.t know he should use the language file?
And uses only enfold.pot?
Jakub

Hi Victoria
thank you.
I found the enfold/lang on serwer and maid some changes but ater uploading I can not see any differences.
Automatic email with content “Your message:” which is sent to person who filled the Contact Form – has no changes.
What do you think – what did I wrong?
best regards
Jakub

Hello Rikard
