Hi Kharis,
Thank you so much for your reply.

I followed up on your guide but the error is still not fixed.

Actually, after the Moesia theme was finished updating, I accessed my website then it shows this error. Afterward, I updated the Site Origin Page Builder plugin and hope it may help this problem.

Would you please help me with another solution to fix this error?
Below is the full error which is shown on my website:

Fatal error: Uncaught Error: Call to undefined function wp_body_open() in /home/tahacomv/public_html/wp-content/themes/moesia/header.php:21 Stack trace: #0 /home/tahacomv/public_html/wp-includes/template.php(704): require_once() #1 /home/tahacomv/public_html/wp-includes/template.php(653): load_template('/home/tahacomv/...', true) #2 /home/tahacomv/public_html/wp-includes/general-template.php(41): locate_template(Array, true) #3 /home/tahacomv/public_html/wp-content/themes/moesia/page_front-page.php(6): get_header() #4 /home/tahacomv/public_html/wp-includes/template-loader.php(77): include('/home/tahacomv/...') #5 /home/tahacomv/public_html/wp-blog-header.php(19): require_once('/home/tahacomv/...') #6 /home/tahacomv/public_html/index.php(17): require('/home/tahacomv/...') #7 {main} thrown in /home/tahacomv/public_html/wp-content/themes/moesia/header.php on line 21

Thank you!
