400 Error when publishing

Hi @keerwebdorks

Thank you for contacting Elementor Technical Support. Based on the provided screenshot and the explanation of the issue, I would suggest the following troubleshooting steps:

• Please check the server resources and ensure there is enough memory to handle update requests.
• If not already set, change your permalink format to Post Name and save settings.
• Please temporarily deactivate any browser extensions you may use to ensure they aren’t affecting the page update process. You can also try editing and updating the page from your browser’s incognito/private mode.
• Check the size of the media files you are using on this page. Large file sizes can cause this problem.

I understand that you pointed out that issue isn’t present after deleting some containers on the page. Could you please try to narrow it down to whether the issue is related to some specific container or widget? If you find the culprit like this, please try to recreate that container or widget and see if it resolves the issue.

Kind regards,

Hi Nemanja,

-For the server resource, how can we check it on the website?
I have attached a screenshot from the cpanel below. Is this the server resource? It seems to be okay.

In addition, there are these few lines of error which I am not sure why is happening:

-Permalink is currently set to Post Name.

-Edit and update in incognito does not resolve.

-The media files I am using on this page are not extremely big.

-It seems that the issue occurs not with any specific container, but when I add containers/widgets beyond a certain limit. E.g. when I delete containers, and add an additional ‘Header’ widget, I am not able to Publish.

@keerwebdorks Thank you for your reply.

From the looks of it, this is probably a server resource limitation issue. Can you reach out to hosting provider and ask them to check error logs for the page and let you know what error do they see. Also, ask them to increase php timeout, increase memory limit of your site, increase database connection limitation which is probably causing this issue.
