Hey Maneschka,
I took a look at your menu, and it looks like your css is working correctly, but the reason your menu is not transparent is because your rgba color code is .85, which is closer to a solid color that a transparent color.
Please try adjusting to .5 like this:

/* Menu area background */
#top #wrap_all .av-burger-overlay-scroll {
background-color:rgba(255,255,255,.5)!important;
}

If this doesn’t help, please include a admin login in the private content area so we can take a closer look.

Hi,
You can use this css in your Enfold Theme Options > General Styling > Quick CSS field
to make this element full width:

#top.home #after_section_9 .container {
    padding: 0px !important;
    margin: 0px !important;
    min-width: 100% !important; 
}

but I recommend adding a custom ID to the element and then replacing “after_section_9” with the new ID in the code above.
This is because this ID could change if you edit the page or add more elements.

Best regards,
Mike

Hi,
It is great news that you found out that it was the avis.js causing the issue.
I can try to compare your modified avis.js with the v4.0.7 version to determine what you were trying to do back then.
Once we know that, you will be able decide if you want the add the modifications to the current version.
Please upload the modified file via Dropbox or Google Drive so I can compare, I have a copy of v4.0.7 to work with.

In your last post you indicated that your live site has the error, even though you removed to custom files. I have checked and don’t see the error, so I assume you have corrected the issue, or the server cache has been cleared?

Hi,
To change the font color of the button with the boarder, try this:

#top .avia-button.avia-color-dark {
color: #ec0928 !important
}

As for vertically centering the text on the buttons site wide, we will need to make them more uniform, on the one page there are 3 different buttons, with 3 different heights.
Please try this css:

.avia-button.avia-size-x-large,.avia-button.avia-button-fullwidth,.avia-button.avia-size-large {
    padding-top: 12px !important; 
}
.avia-button-wrap.avia-button-center,.avia-button-wrap.avia-button-left {
height: 45px !important;
max-height: 45px !important;
}

Best regards,
Mike

Hi,
Did you find the second code snippet to help with centering the text vertical after clearing your cache? I just took a look and it seems to be working.
To make it site-wide, please remove the page ID from the code (.page-id-4359)

Best regards,
Mike

Hi,
For the border, please remove the css I gave you and replace it with this css:

#top.page-id-4359 .avia-button.avia-color-dark {
    border-color: #ec0928 !important; 
}

To center the text on the buttons, please try this:

#top.page-id-4359 .avia-button.avia-size-x-large {
    padding: 11px 50px !important; 
}

}
}
@media only screen and (min-width: 480px) { 
#top.single-product .single_variation_wrap .npay_storebtn_bx{
    margin: 0px !important;

}

    width: 30% !important;

}
}

Hi,

Hey Enis,
Thank you for the images, First please explain how you updated, via ftp?
If so, please note that overwriting the theme files will cause errors because old files will be left behind. You would need to delete the enfold parent theme folder and then upload the new enfold folder.

If this is not the case then:
I see in your child theme you have a copy of avia.js which would be from v4.0.7 and could conflict with the newer version. When you took the screenshot above was the child theme activate?
Typically the only reason to add a file to the child theme is because there are customizations made to it, what changes were made to yours?

Did you restore your site with a backup? If so, please try exporting your theme settings at Enfold Theme Options > Import/Export > Export Theme Settings File
and then install the new version of the enfold parent theme, and import your theme settings.
Then please check that the Enfold Theme Options > Performance > Disable Template Builder Elements > Always load all elements is set, and Enfold Theme Options > Performance > JS & CSS file merging and compression is disabled, then check your site.
This should look like your child theme without activating it.

Doing this will ensure the custom files in your child theme are not causing the error.
Let us know if you still have the error, and restore your site so you won’t lose visitors.

If you still have this issue, please check your webhost to see if you have the one click staging site option, this is a option in most cPanels to create a staging clone of your site so we can test on it and you site will stay up and running. You can always ask your webhost to help you with setting this up if you want.
Here are some screenshots of what it would look like:

Hi,
If you updated though WordPress then this would not be the issue, so no need to delete the theme files.
I will take another look at the posts and see if I can find the error, if not I will ask the rest of the team to also take a look too.

Best regards,
Mike

Hi,
If the template contains a error, such as the missing/extra strong tag, and it is used to create other pages, then it would carry the error to those new pages.
If the template has no errors, then it will work correctly.
Have you seen similar errors on other pages?

Best regards,
Mike
