I read forums related to webstories on wordpress and tried advices given like installing Health Check & Troubleshooting plugin. > activate it> enable webstories plugin > and checked if the webstory could preview but the same problem persists in default theme. Then I rolled back to my installed theme.

I have the below relevant setting in my webstory.:-
Stories Archives – set to default (I don’t know if this is casing problem)
I have the below message shown in plugins page (letting you know if this is relevant) :-
Rank Math has detected a new post type:?web-story. You may want to check the settings of the?Titles & Meta page?and?the Sitemap.
It is killing my time. please suggest me some solutions.

I built my website on Neve using Elementor and Elementor header & footer builder.
It was working very well on my staging domain dev.living-labs.org

I transferred the website to my main domain living-labs.org. When propagation was over, only a blank/white page appeared. An error in the source code was error-theme.

I now changed to another theme to access backend but lost my UX. If I revert back to Neve, the same error appears.

Can someone help?

mailpoet is not working any more. I installed version 3 – same issue. I started the maintenance mode with standard template and none plugin. same issue.

one the form editor page there is a white page. if i enable the debug mode, the following errors appear:

what can i do?

When I click on a link (internal or external) a blank page with ‘x’ in the upper right corner appears. If I right-click and try to access pages that way it works.
I use the simpleMag theme and I’m on WP 5.6 (I downgraded unpurpose but didn’t solve the problem)
I already tried deactivating all the plugins, didnt’ work and I’m not using the lightbox plugin, which seems to be a problem for others.

Also the images in the blogposts seem to have disappeared in the same time…

Here is the the website: https://nord-sud-passage.com/fr/bienvenue/

Thank you for your help in advance!

Thanks, regards.

My web page has stopped loading the editor, it goes blank and widget bar loading.

It has already happened to me on other websites so I have deactivated all the plugins and I have been activating 1 by 1 to see which one fails, it is elementor pro!

It had never happened to me but right now I have only Elementor activated and it works, I activate the Pro and nothing, it fails

Any ideas?

Thank you very much!!!
