, it might be due to the use of non-Latin characters in your child theme folder name. Solution: We recommend renaming your child theme folder to use only Latin characters. Here's how you can do it:
Backup your website.
Access your website files and navigate to
wp-content/themes/
.
Rename the child theme folder to a name with Latin characters, for example:
blocksy-child
.
Go to your WordPress dashboard, under Appearance > Themes, and reactivate your child theme.
I have checked the website on the copied version and the same issue is happening there.
This suggests that the issue is happening because of the migration and it is not related to a code or something.
Most probably something is wrong in the database as the issue happens as soon as Elementor is enabled and that shows the content inside the database might have a mismatch due to migration.
I suggest that you do a migration using another plugin and see the result.
You can use one of the plugins listed here other than the Vivid plugin:
Would you please provide the login information to the dev version of the website that is working ok? Please make sure you set the next reply as private.
I will try to do the migration to our server from there and let's see what will be the result.
The problem is the child theme folder.
It is "%d8%a8%d9%84%d9%88%d9%83%d8%b3%d9%8a-child" and this creates the problem because we try to parse a path which contains 14 arguments that we expect them to be filled.
Please rename the name of the child theme folder to a latin normal characters.
The issue is the name of the theme which is not in latin words. You should change the name of the theme to normal one.
Access your website files. Go to wp-content/themes/ and you will see what I mean (Check the screenshot)
The name of folder should be in latin not Arabic characters (which then turns into those characters as some servers can not handle non latin folder names).
Please backup your website, change the folder name to for example: blocksy-child
Then go back to Appearance > Themes and activate your child theme again and it should work
