It does not save the edited content of the pages or templates, and provides an error message.

admin/index.php?module=editor/editor&name=Home&url=/page/home&template=blank.html

When I create a web page or edit any content, or templates, I can't save it and an error message appears. Also, sometimes I can't upload files; it says I don't have administrator permissions.

I'll look at the code to help, but I don't have much information or reference.

Can you please share the error message that shows on page save?

The error is shown only on newly created pages or also for previously exising pages?

Can you please try to update to the latest release from admin > tools > update > force update there are some recent fixes made to editor.php code that might be related to this bug.

The upload permission error is shown for super admin user/role? the upload is done from media library page or from post/product page etc media modal?

It only displays the error title in red and there is no other content; sometimes it's a single window and other times two.

The error occurs in both new page and existing versions when updating, especially with the visual editor.

In the previous version I could track the error and provide a solution; now it's just a title.

The error in uploading files is no longer a problem; I changed the folder permissions on the server, but the error of saving a new folder or updating an existing one is permanent.

Can you also try to change folder permissions for the theme files in public/themes/landing?

Probably the error message is missing because of a php warning that breaks the json response.

Can you please check the server response after page save from browser developer tools (F12 key) network tab
