Hi jasperkeyplay,
Thanks for reaching to us.
A 403 error typically indicates that the server is blocking certain requests. This issue is likely related to server configuration or restrictions set by your hosting provider.
Follow the article below to fix that: https://www.wpbeginner.com/wp-tutorials/how-to-fix-the-403-forbidden-error-in-wordpress/
We recommend consulting with your hosting provider to determine why these specific requests are being blocked. They should be able to review the server logs and identify the exact cause of the issue.
In the meantime, we advise against setting permissions to 777 as it can pose a security risk. The recommended permissions for WordPress files are usually 644 for files and 755 for directories.
Kind Regards,
Hung PD
