The theme update from version 1.6.1 to version 1.9 causes a number of error messages and incorrect display. Also it doesn’t work with PHP 8.2, also not with PHP 8.1, PHP 8.0, and PHP 7.4. Only the completely outdated and unmaintained version PHP 7.3 works. That can not be true! In addition, the parallax effect no longer works and the pages (5 pages from 9 at my homepage) remains blank, it does not display any images. So please help soon. Thanks

I was able to fix some problems with the parallax effect myself. But not the error messages with a higher PHP version than 7.3. Since I have two Dalton licenses for two websites, I ask for a quick remedy.

The Internet warns against using the PHP 7.3 version:

“As of December 6, 2021, PHP 7.3 will no longer be supported by the PHP community. Therefore, it is important to upgrade to a higher version now. If you have PHP 7.3 running on the server after the “end-of-life” date, you are defenseless against newly discovered security gaps. In the worst case, there is a risk of inaccessible websites and data theft.”


Hi. I have a problem with PHP 8.x, when I switch to 7.4 to 8.x the website crashes. Everything is up to date (Theme, WP, plugins) but I saw that 2 plugins of yours (Dalton Custom Posts and Dalton Shortcodes) can’t be updated, maybe the problem comes from there. Are your theme and plugins compatibles with PHP 8.x?


Hi! How do I get support for this theme?

When I access the website with a smartphone the navigation/header is messed up. Also every first letter of H1, H2 etc is capitalized and I can not turn it off.

I have just updated to the latest version of this theme.

Thank you so much!

Hello there,

I need a key for the “Slider Revolution” that comes with the Dalton Theme. Where can I find this?

Kind regards Stephan

Hello Stephan,

Thanks so much for your purchase.
You can’t activate the Slider Revolution plugin. It’s just bundled with Dalton.
You can let me know if you want the latest version.

Kind Regards!

Hello, I have a problems with version 1.8. I have updated to version 1.8 from 1.7 and the Dalton options of the wodpress panel shows empty. The page builder doesn´t work too. Thank you.

Hello ZoomArts Team, I just wanted to ask if this theme exist in a non-wordpress version ? Thanks a lot


dukon Purchased

the REDUX-FRAMEWORK stopped working I can not change theme options anymore

Fatal error: require_once(): Failed opening required ’/web/htdocs5/ekosadykomnacz/home/www/wp-content/plugins/redux-framework/redux-core/appsero/Client.php’ (include_path=’.’)

I had to remove redux-framework to get the website alive.


dukon Purchased

I have figured it out, it was auto-update plugn option…. which version of REdux shall I download from here?https://pluginarchive.com/wordpress/redux-framework

I have tried 3.6.4 but it generates some warnings though….

Hi, my site’s default paragraph text has defaulted to serif, even though I have Open Sans set in Typography > Main > Body: www.conversiontown.com

How do i stop the featured image appearing in the portfolio items? Example: https://conversiontown.com/portfolio/eu-tendering/

How can I hide category, author name, and date of published post? I tried code you gave to someone in the comments but it but didn’t work: .post-head .post-meta { display: none!important; }: https://conversiontown.com/blog/

How can I remove the dotted box on latest projects carousel (next to the arrow on bottom-right of image that when you click it opens the jpg): https://conversiontown.com/portfolio/


Is there any update on the theme to be released soon? There are some bugs (background images or colors not showing…) to be fixed that makes the theme useless

Broken design after update

Exactly the same thing happens to me as @c2quadrat. I updated wp, plugins and Dalton theme. Then much of the design disappeared; background images or column colors vanished though it appears in the edit page. I’m not going to renew support for something that worked fine and should keep working after updating. A solution is mandatory; and possible customers should be warned.

Hi I’m a Dalton theme usser.

I can’t fix a custom logo dimensions. I change logo dimensions on the header tab in Dalton options, click on save changes button, and always returns to 101×31 px.

How can I fix this?

Thansks in advance. Jesus

I really like the Dalton Theme but there are more and more errors.

My Dalton Theme is still on version 1.6.1, because any update destroys my entire appearance. When I update to 1.7.1 my page sits as a block in the middle instead of the full width of the page. My logo in the header is gone, instead the one from Dalton appears. The footer has completely disappeared, Google Map is not displayed (API is valid, there is a big white space instead of the map)....., and much more layout faults. My website is complex and I cannot list all of the errors.

1 year ago I already spent a lot of time and money on getting the site to run with PHP 7.3 at all. I’ve had a myriad of error messages.

The update to PHP 7.4 reports on almost every page: Warning: Creating dafault object from empty value

PHP 8.0 is now strongly recommended. An update to PHP 8.0 shoots the page completely with fatal errors.

Fatal error: Uncaught Error: Call to undefined function create_function()

So please, how can all of these errors be fixed, so that my site is running on PHP 8.0, showing how I set it up, and displays google maps again.

I’m having issues with Slider Revolution 6 Slider responsiveness. The slider doesn’t fill the page. It appears to to stop short of the right like there’s a margin value, but when I resize the window the slide jumps to fill in the space and the page looks like it should. Website: nxtmortgage.com I have sliders on almost all my pages so this is a big issue. What do you suggest to correct it?

Thanks, Kromys


I’m having issues with the latest Slider Revolution 6.5.4 – the slider doesn’t appear to load correctly consistently. I have the sliders set to Full Width and Auto but the carousel and scene sliders seem to load with a margin on the right side of the viewport. But when you resize the window the slider snaps to the correct size.

It appears to work fine when inspecting the window and choosing responsive (most of the time), but when I’ve tried to load the different pages of my website in incognito mode in Chrome and Safari I get the issue. Again it is very inconsistent, I’m also on the latest version of both browsers.

Hello, would you be able to have a video as the header for this theme?
